Proxy Routes and Protocols

Connection Layers: Pinpoint the Problem

Apps, Proxies, and the Network Path

A request starts in an app, then passes through name resolution, connection setup, and data transfer before the destination service returns a response. The client receives requests that match its rules and sends them through the selected route. The protocol defines how the client and server identify a connection, encapsulate data, and handle authentication. The route determines the path the data takes to its exit point. These parts are related, but they are not interchangeable. Changing the protocol does not automatically change the exit region, and changing the exit does not necessarily improve the quality of your local Wi-Fi.

When diagnosing an issue, first identify where the failure occurs. If the client will not start, check system permissions and the app's status. If the subscription imports but a node will not connect, check the node details, local network, and transport compatibility. If the route connects but a particular site fails, check the rules, name resolution, destination service status, and account requirements. A connection icon in the client does not prove that every app is using that route, or that the destination platform has accepted the request.

Separate Connection Setup from Ongoing Data Transfer

Connection setup involves domain name resolution, the underlying transport handshake, encryption negotiation, and proxy authentication. A slow first page load may be caused by any of these steps, or by the app making requests to several domains in sequence. Ongoing downloads depend on throughput, congestion control, and retransmission efficiency. A route that handles downloads well may not deliver a fast first byte for small requests; conversely, a page that opens quickly does not tell you how large file transfers will perform. Test with requests that resemble your actual tasks rather than relying on a single metric.

Latency tests in clients can measure different things. Some check whether the entry point is reachable, some send a test request through the proxy, and others include handshake time. Since targets, timeouts, and connection reuse vary, the results are not directly comparable. If results change in the same client, check for background downloads, system updates, or changes in Wi-Fi signal during the test. Latency is useful for an initial comparison, but it cannot tell you on its own how an app will feel to use.

Subscription Details and Service Capabilities

A subscription contains nodes and related settings for import into a client. It may include a region, address, port, protocol, and authentication details. Nodes with the same protocol name can still use different transports, certificate settings, and server policies. Changing a node's protocol field by hand does not convert it; it can instead invalidate otherwise correct settings. For everyday use, keep the configuration provided in the panel. Understanding the technology and editing a live configuration are separate tasks.

This page covers Shadowsocks, VMess, Trojan, VLESS, Hysteria2, and TUIC to provide a framework for comparison. It does not mean that every VPNBasic route supports all of these protocols. Check the user panel, your current subscription, and what your client detects for the available options. Labels such as dedicated, relayed, or direct describe how a route is organized; they do not replace the protocol field. A sound choice takes the app's needs, client support, route topology, and current network conditions into account.

Ask “where does the request stop?” before asking “which protocol should I switch to?” Mixing up connection failures, slow connections, and destination service denials leads to wasted troubleshooting.

A brief usage log can help: note the current network, client name, selected region, protocol, app behavior, and error message. Do not save authentication details. When retesting, change one thing at a time. For example, keep the region the same and switch route type, then keep the route the same and compare client modes. This helps identify which layer caused the change and makes it easier to describe a reproducible issue in a support ticket. Before sharing a screenshot, hide subscription URLs, QR codes, and account details.

Common Protocols: Authentication, Encryption, and Compatibility

Choosing Between Shadowsocks and VMess

Shadowsocks is an encrypted proxy transport with a relatively focused design. Client implementations and cipher suites can affect resource use and compatibility. When assessing it, distinguish the protocol itself from optional plugins. A plugin can change the outer transport and introduce additional handshakes, dependencies, and troubleshooting steps. A short protocol name does not mean every implementation is lightweight, and the behavior of one older implementation does not define the whole protocol family.

VMess has its own authentication and data encapsulation mechanisms, and deployments may use different outer transports. Availability depends not only on server support, but also on the client implementation, system time, and matching parameters. If the device clock is significantly off, some authentication flows may fail. If a subscription imports but authentication fails, first make sure automatic time synchronization is working. Do not assume an authentication failure is congestion: they require entirely different fixes.

Security Considerations for Trojan and VLESS

Trojan typically uses TLS for encrypted transport and handles proxy authentication within it. The important details are whether the certificate is validated correctly, the server name matches, and the client fully supports the configuration. Disabling certificate validation as a temporary workaround weakens server identity checks and is not a routine fix. If you see a certificate error, check the system clock, subscription status, and exact error message, then report it through the panel. Do not accept an unknown certificate without checking it.

VLESS focuses on authentication and forwarding at the protocol layer; it does not, by itself, provide a complete encryption guarantee inherent in its name. It is usually best understood alongside an appropriate secure transport. To compare VLESS with Trojan, compare the complete configuration rather than just the protocol labels. Outer security mechanisms, connection reuse, client cores, and server deployment all affect the result. For most users, a complete node provided in the panel and clearly supported by the client is a safer choice than picking a protocol name in isolation.

How to Compare Overhead

A fast connection setup usually means less waiting before an app request can be completed. That wait includes protocol negotiation, network round trips, and server processing. If the destination is far away, reducing some encapsulation overhead may not noticeably improve the overall experience. Resource use also depends on hardware acceleration, the client implementation, concurrent connections, and log level. You cannot establish a lasting speed or memory ranking for protocols without accounting for the device and configuration, or apply a desktop test result directly to a mobile device.

Connection reuse lets multiple requests share an underlying connection, reducing repeated setup work. It can also make more requests depend on the same connection state. If the network fluctuates, several requests sharing one connection may be affected at once. And if the app already uses a connection pool, extra reuse may offer little benefit. Do not enable every option labelled “reuse” just because it is available. Start with the subscription defaults. If you have a clear issue with many short-lived connections, check the client documentation and test settings one at a time.

If a node works only in a particular client, consider implementation differences before repeatedly changing passwords. Check whether the client parsed the subscription correctly, whether it missed a secure transport field, and whether its core supports the configuration. After updating the subscription, keep the original error message and compare it with a known-working route. Any changes to protocol options should be reversible. Leaving unexplained settings alone is more likely to produce a reliable diagnosis than layering on several supposed optimizations.

QUIC Protocols: Benefits on Unreliable Networks and When to Use Them

What Hysteria2 and TUIC Are Designed to Do

Hysteria2 and TUIC are both related to QUIC technology over UDP, but that does not make them the same protocol. They differ in authentication, session management, congestion control, and implementation. QUIC combines reliable transport, encryption, and multiplexed streams, offering a different way to handle multiple types of traffic. Real-world performance still depends on the client, server, and network path. A protocol name associated with newer technology does not guarantee it will outperform established alternatives.

Data within a traditional TCP connection is delivered in order. If a segment is missing, later data may have to wait for it to be recovered. QUIC's independent streams can reduce some of the waiting between streams, but each stream still has to handle packet loss and ordering, and all streams still share the network's actual capacity. It is inaccurate to say that packet loss “doesn't matter.” QUIC improves some waiting relationships; it cannot create capacity on a congested link or fix persistent Wi-Fi dropouts.

UDP Reachability Is Essential

Before using this kind of solution, confirm that your current network allows the relevant UDP traffic. Some networks handle UDP differently in terms of forwarding, rate limits, or session timeouts. This can lead to failed handshakes, disconnections after idle periods, or unstable transfers after the connection is established. If other transports work in the same region but QUIC-based nodes keep failing, keep a compatible alternative for comparison. Do not move all apps to the same type of node before checking reachability; you could lose your way back to a working connection.

QUIC connection setup can be affected by mechanisms such as session resumption, so a first visit and a repeat visit may have different setup overhead. When comparing results, distinguish a cold start from an existing session, and check whether the app reused its previous connection. Some early-data mechanisms have their own security constraints; you cannot tell whether the client uses them or the server allows them from the protocol name alone. For everyday use, check that both reopening the app and using it continuously work as expected instead of chasing the theoretically shortest handshake.

Bandwidth Settings Are Not Actual Capacity

Some implementations offer options for bandwidth estimation, congestion control, or sending behavior. These settings influence how data is transmitted; setting a larger number does not make the route faster. Overestimating capacity can push data faster than the link can handle, creating queues, packet loss, and extra retransmissions. Underestimating it can limit actual throughput. Unless you have a clear reason to change them, use the settings provided in the panel and the client's defaults. Do not copy parameters from a different network or use your plan's data allowance as a bandwidth value.

QUIC often handles more transport logic in user space, so CPU use, battery drain, and heat vary by implementation and device. A lower-powered device, strict background limits, or frequent network switching can produce different results from a desktop. If the device gets noticeably warm during sustained transfers, first rule out factors such as screen brightness, video decoding, and app updates, then compare another route using the same task. UDP alone does not imply lower battery use, and heat alone does not prove a protocol issue.

QUIC-based options are worth considering, but keep a tested, compatible route available as well. Check reachability, task completion, and resource use before focusing on protocol labels.

If a QUIC-based node connects but some content stalls, test small requests and sustained transfers separately. If small requests work but larger transfers fail, the issue could involve how the path handles packet sizes, congestion behavior, or server state. Check the client's diagnostic information. Do not lower settings for every app or copy network parameters at random. Switch to a known-working route to confirm the app itself works, then report the exact failure stage and error message.

Compare Hysteria2 and TUIC based on the complete end-to-end experience: the same device, network, approximate region, and task. Note whether reconnection is needed, whether the connection recovers after returning from the background, and whether long requests finish. This page does not rank them outside a specific environment. If the panel does not offer a protocol, do not manually assemble a node that merely looks similar. Whether it works depends on the actual configuration and support on both ends; a technical overview is not a list of services included in your plan.

Route Topology: Direct, Relayed, and Dedicated Routes

Path Length and Path Quality Are Not the Same

A direct route usually means the client reaches an overseas service entry point through its current network, without an additional forwarding entry point managed by the provider. “Direct” does not mean the physically shortest distance: data still travels through carrier networks, interconnection points, and routing decisions. The structure is easier to understand and has fewer steps, but performance depends heavily on the interconnection quality between your local network and the destination region. A short distance on a map does not guarantee a short network path or stability during busy periods.

A relayed route sends data to an entry point first, which then forwards it to the next node. An additional hop can add processing and path length, but a better interconnection can also improve the end-to-end experience. What matters is whether the entry point is reachable, the later path is stable, and the capacity of each segment is well matched. A relay is not inherently slower than a direct route, and direct is not inherently more efficient. Evaluate the complete path rather than counting the steps in its name.

Evaluate an IEPL Dedicated Link as Part of the Full Route

An IEPL dedicated link describes a type of route organization using a dedicated Ethernet connection, often for a particular segment of the path. Even when one segment uses a dedicated link, local access from the client to the entry point, the network from the exit to the destination platform, or the app itself can still be a bottleneck. Do not extend a characteristic of one segment into a guarantee for the entire connection. When choosing a route, identify which segment the dedicated link covers, then test whether both the entry and exit work for your current network and use case.

Different route types may share some underlying infrastructure. Nodes with different names may use similar entry points or the same exit resources. When troubleshooting, switching between several similarly named nodes may not provide a useful comparison. Instead, change one clear variable: the entry point arrangement, the region, or the network you connect through. This can help show whether a shared part of the route is the problem, rather than simply building a list of failed node names.

Choose a Region with the App's Requirements in Mind

Region affects both round-trip distance and the exit location seen by the destination service. Work systems may require consistency with the region commonly associated with an account. Streaming content may vary by region and account requirements, and some AI tools have their own service areas. A region label is not a promise that every service will work there. Check the destination service's access requirements first, then choose a suitable region. Frequent exit changes may trigger additional account checks, so keep the region consistent during long tasks.

VPNBasic covers 100+ countries and 190+ routes. Check the panel for the routes currently available. This coverage gives you options; it does not mean every region will perform the same on every network. When browsing the route list, consider the region, route type, and use case together. Examples in the list do not confirm availability in a particular city at a particular moment. For long-term use, test and keep one primary route and one backup rather than collecting a large number of untested nodes.

When reading route details, distinguish the entry address, exit region, and client display name. The entry point is where the connection starts; the exit is the network location seen by the destination service; the name may simply be a convenient label. Seeing an entry address associated with a particular location does not prove the exit is there too. To check the actual exit used by an app, run a network check after connecting and verify the target app as well. A browser and a terminal may use different rules, so the result only describes the route used for that request.

Congestion and Packet Loss: Understanding Slowdowns

Queueing Delay and Bandwidth Contention

Network links have limited capacity. When incoming data consistently exceeds what can be sent in time, devices queue or drop packets. Queues add delay, and an overflowing queue can trigger retransmissions. This may look like a page that never responds, choppy audio, or sluggish remote controls. A speed test may still show good download throughput because a large transfer can keep the link busy. If you only look at throughput and ignore responsiveness, you can miss the queueing problem that affects everyday use.

Upload capacity matters on home networks too. Cloud sync, photo backups, and file uploads can use the upstream bandwidth and delay acknowledgments and interactive requests. Users often notice downloads but miss ongoing background uploads. To troubleshoot, pause nonessential sync, check whether other devices are transferring data, and see if pages or remote sessions improve. If pausing background tasks helps, focus on local bandwidth contention before switching regions or changing protocols.

Busy Evening Periods Do Not Point to One Fault

Busy evening periods can affect Wi-Fi access, local carrier networks, inter-network links, relay entry points, or exit resources at the same time. Congestion in different places can produce similar symptoms, so “it’s slow at night” does not identify the cause. On the same device, compare commonly used local sites with the target app, then switch access networks without changing the route. If local sites are slow too, start with the local network. If only a particular route has issues, compare another path or region.

Congestion is not the only cause of packet loss. Wireless interference, weak signal, network switching, device load, and packet handling along the path can all contribute. Transport protocols try to recover, but recovery takes time and uses extra data. Some tasks are sensitive to delay; others can hide brief interruptions with buffering. So it is not contradictory for video to seem fine while an interactive tool stutters on the same network. When comparing tasks, distinguish content that can buffer from actions that need an immediate response.

Buffering, Retransmissions, and App-Level Retries

Transport-layer retransmissions recover missing data; an app-level retry may restart the entire request. If the app retries a long generation, upload, or remote operation, it may repeat work. Do not assume the task failed just because the client still shows as connected. After an interruption, first check whether the app is still working and whether it returned a task ID or saved a draft. For actions that can have external effects, check the result before retrying. A recovered connection does not mean the task never ran.

Interpret packet-loss results from diagnostic commands carefully. Devices along the route may give diagnostic packets lower priority, so a hop that does not respond promptly is not necessarily dropping forwarded traffic. If a later hop responds normally, one missing intermediate response alone is not evidence of a fault. Stronger evidence comes from persistent issues at the destination that match failures in the actual app. Most users do not need a complex route map; clear notes about the failed task, time, and comparison results are often more useful.

Record “route connected,” “diagnostic request succeeded,” and “task completed” separately. Each checks a different part of the process; none can stand in for the others.

Keep conditions consistent when retesting. Use the same device, app, region, and task; pause background traffic before comparing another route. If you then switch networks, record that as a separate change. Do not change the protocol, region, client, and network mode all at once. Even if the issue clears, you will not know which change helped. Avoid repeatedly running large speed tests to check for congestion: they consume resources and may interfere with apps already in use.

If an issue occurs only during busy periods, test a backup route ahead of time rather than searching for one after a task is interrupted. Check whether real pages load promptly, remote sessions remain responsive, and long requests finish. If several different paths fail on the same access network but work after you switch networks, focus on the local network. If only one destination platform has issues, check its status, region requirements, and account session instead of attributing everything to congestion.

Platforms and Battery Use: How Clients Affect the Experience

How the System Handles Traffic Determines Its Route

System proxy settings, in-app proxies, and tunnel mode are different ways to route traffic. A system proxy provides settings to apps that honor them; not every program does. An in-app proxy affects only that app. Tunnel mode uses a system network interface to handle a broader range of requests, but is still subject to rules, routing, and permissions. If a browser works but a terminal does not, first check whether they use the same connection method rather than assuming the node cannot support terminal tools.

Name resolution can also happen in different places. Some apps resolve names locally before sending the address through a proxy; other modes send the domain to be resolved by the proxy. Different resolution paths can lead to different app behavior. Before changing DNS, check the client's current mode and documentation. Avoid installing multiple tools that alter network settings. Old proxy addresses, tunnel interfaces, or name-resolution rules left on the system can make a new client appear connected even when requests are still taking the old route.

Differences Between Desktop and Mobile Devices

Windows and macOS use different system proxy, permission, and network extension mechanisms. Linux desktop environments and command-line tools may also have their own proxy settings. A button name shown in instructions for one platform may not apply to another. Check that a permission prompt comes from the client you are using and understand what it is for. VPNBasic supports Windows / macOS / iOS / Android / Linux. See the client setup guides for import steps and permission prompts.

Mobile devices are more affected by sleep, background policies, and network switching. When an app moves to the background, the system may limit its activity. Switching from Wi-Fi to mobile data may also require existing transfers to reconnect. Some QUIC features can help handle address changes, but smooth recovery still depends on the implementation and network conditions. “Supports connection migration” does not mean every switch will be seamless. Keep important uploads and long sessions on a stable connection where possible.

Battery Use Comes from Ongoing Activity, Not a Protocol Name

Encryption, packet handling, connection keepalives, and repeated reconnections all use resources. Screen use, app decoding, and network signal quality also affect battery life. A weak signal can cost more power to maintain a connection than the differences between protocols. To compare battery use, keep the task and device conditions similar and use the system's battery statistics rather than relying on feel. Blaming every drain on the client can overlook more direct causes such as background backups, app updates, or continuous playback.

Log level and probe frequency are also worth checking. Detailed logs help with short-term troubleshooting, but recording a large number of requests continuously can increase storage and processing load. Automatically testing many routes over and over also creates extra network activity. Keep only the diagnostics you need for everyday use, and temporarily increase logging when troubleshooting according to the documentation. Restore normal settings afterward, and check logs for authentication details, private domains, or other information that should not be shared before sending them to anyone.

VPNBasic allows unlimited simultaneous devices, but that does not mean your home network capacity or plan data will not be shared. Syncing, streaming, and downloads across multiple devices can affect each other, so plan around your actual tasks. Get the client and subscription through the user panel after signing in. iOS availability is subject to the conditions shown in the panel. Do not share your subscription with untrusted devices or paste the full subscription into a public forum to make troubleshooting easier.

Use Cases: AI Tools, Streaming, and Remote Work

AI Tools Need the Entire Request Chain to Work

The experience with AI tools depends on more than whether the site opens. Sign-in, content generation, file uploads, model APIs, and resource loading may use different domains or connection methods. If the home page works but generation fails, check the specific request stage. First confirm account status, service availability in your region, and any message from the platform. Then check whether the app's requests are using the expected route. Do not mistake a platform limit, permission, or maintenance notice for a network issue that switching protocols will fix.

Long text generation often streams a response over time, so if the connection stalls, the page may still show some of the content already received. Check the final status and complete output to confirm the task succeeded; text appearing at the beginning is not enough. Keep the exit region and network consistent during long sessions, and avoid switching routes manually. If the connection breaks, save the content already returned and check the task status before retrying. For tasks with attachments, confirm the platform received the file.

Test Developer Tools and Terminal Separately

Tools such as Cursor and Copilot may use an editor interface, background processes, and extension requests. Package managers and version control tools in a terminal may use separate settings. Successfully signing in through a browser does not prove every part of a development workflow is connected. Test inline completions, chat, dependency downloads, and repository access separately, and note the specific error. Certificate validation failures and connection timeouts need different fixes; disabling certificate checks is not a way to hide a network issue.

For command-line proxies, follow the documentation for the tool in question. Check which settings it reads, whether it inherits the current session environment, and whether a background process must restart to apply changes. A browser extension is not a terminal proxy, and a local proxy address is not the same as a remote subscription URL. For more on setting up a development workflow, read Choosing a Route for AI Coding Tools. The goal is reproducible network conditions, not a different exit for every process.

Streaming and Remote Work Need Different Metrics

Streaming relies on buffering to ride out brief disruptions, but picture quality, adaptive playback, account entitlements, and the platform's region checks all affect the outcome. Access to the platform does not guarantee that a particular title will play, and being able to play a title does not mean every quality level is available. Test with the account and content you actually use. Check startup, sustained playback, and recovery after seeking. Route region is only one factor and cannot guarantee that a platform will remain available.

Remote desktops, voice calls, and collaboration tools depend more on quick responses. They can be sensitive to queueing and jitter even when throughput is low, so a large download test is no substitute for testing interaction. Check whether input responds promptly, audio stays clear, and screen sharing remains stable. Pause background tasks that compete for bandwidth. If you need to switch routes, do it between sessions where possible. Changing the exit during important collaboration may force a reconnect or trigger a session check.

Choose routes by task completion: check the full response for AI, actual requests for developer tools, sustained playback for video, and responsive recovery for remote work. Different tasks do not need to share one metric.

Grouping everyday tasks can help avoid conflicting settings. Keep a stable route for work sessions that need a consistent region. Avoid running large, bufferable transfers alongside real-time tasks. For occasional apps, start with rules that have already been tested and investigate separately if they fail. Do not change every traffic mode and DNS setting to get one app working temporarily. Know which traffic each change affects and how to restore the original setting, or later issues will be harder to diagnose.

Technical choices should also respect the destination service's terms. Region, account eligibility, and content licensing are determined by the platform; a proxy protocol cannot replace those requirements. When reading the streaming route guide, record the platform's actual messages separately from route performance. If you need help, describe the exact stage, such as “sign-in works, playback fails” or “small requests work, but generation stops.” This is more useful for troubleshooting than saying a platform does not work.

Choosing a Route and Troubleshooting: Keep Useful Records

Set a Baseline First, Then Keep a Backup

Start by establishing a baseline on a familiar device and a stable network. Import the subscription provided in the panel, keep the default security settings, choose a route that meets the app's region requirements, and complete a real task. Once you have confirmed the app works from start to finish, compare other protocols or paths. Do not investigate numerous settings before the basic workflow works. If client import or permissions are unclear, return to the Guides and complete the installation and testing steps first.

You do not need a complex dashboard to compare results, but do keep useful context: device and operating system, client, access network, region, route type, failure stage, and whether you can reproduce the issue. Describe observations as facts, such as “file upload completed” or “reconnecting was required after returning to the app,” rather than just “fast” or “stable.” Test your backup route in a real app. Ideally, it should differ from the primary path in a clear way, so a failure does not leave you switching to another entry point with the same issue.

Choose the Next Step Based on the Failure Stage

If you cannot establish a connection at all, first check your account and subscription status, refresh the subscription, and confirm the system clock. Then compare another route. If only one type of transport fails, check whether the current network supports it. If every route fails, check local connectivity, client permissions, and whether another tool has changed network settings. If the client connects but only the target app fails, look at the app's proxy method, rules, and name resolution rather than repeatedly importing the same subscription.

If the connection comes up but the task stops partway through, check whether the system went to sleep, the access network changed, or the app was stopped in the background. Keep those conditions the same and retry on another route you have already tested. If only a specific task fails, check its upload, destination permissions, and service status. If all long transfers fail, use the client error to investigate the path, packet handling, or congestion. Deleting all settings should not be your first step; without the evidence, you may still not know the cause after restoring them.

Keep Data Allowance Separate from Protocol Preferences

Choose a plan based on your actual data needs; a higher data tier does not guarantee better performance from a particular protocol. VPNBasic monthly plans are ¥9.9/month for 60GB, ¥18/month for 250GB, and ¥28/month for 500GB. Data resets monthly on the activation date, and mid-cycle upgrades are prorated for the remaining days. Check the pricing page and account for multiple devices and tasks such as extended video playback or file transfers. Do not infer unlisted speeds or route priority from plan prices.

If your usage varies, consider a data package: ¥158/300GB, ¥358/1000GB, or ¥658/3000GB. Data is consumed as needed and never expires. The difference between a data package and a monthly plan is primarily how billing and data validity work; it does not imply any unlisted performance guarantee. VPNBasic accepts Alipay / WeChat Pay / USDT and offers a 7-day no-questions-asked refund. No email address is required; you can create an account with a username and password. Check orders, data, and support requests in the user panel.

Support Tickets and Privacy

If you need help, submit a concise, reproducible report through a user panel ticket: what you did, where it failed, what appeared on screen, what you changed, and the results. You can include a reviewed excerpt of the error, but do not share your password, full subscription, authentication QR code, or private request contents. If logs contain address parameters, check whether they identify your account. If you are unsure, describe what happened instead of posting the entire file publicly.

The end result should be a configuration you can explain and restore, not a set of mysterious optimization settings. The protocol defines how communication works, the route determines how the path is organized, the client controls how traffic enters, and the app and account determine the service requirements. Testing each layer separately helps you know when to switch routes, adjust the client, or wait for the destination service to recover. There is no permanent protocol ranking. A clear baseline, a suitable backup path, and complete records are what make your setup reusable over time.
