Understand what AI tools check first
A page that will not load, a failed login and an interrupted response usually involve different layers. Checking the network path step by step is more effective than repeatedly switching regions.
region.check
Region detection
AI services may use your exit region to decide whether a page is shown, features are available and login can continue. The official site, identity verification pages and subsequent app pages should use routes in the same region to avoid changing the exit location mid-flow.
session.consistency
Session consistency
Login state is tied to cookies, the browser environment and the network exit. Frequent cross-region switching can trigger verification again or invalidate an existing session. During a verification loop, close the relevant pages, fix the route and re-enter from a new browser session.
stream.keepalive
Persistent connections and streaming
Chat replies, code completion and long-form generation depend on continuous transmission. A route that opens the homepage does not guarantee a stable streaming connection. If replies often stop midway, check packet loss, proxy rules, sleep-related network changes and local security software rather than only the initial page-load speed.
endpoint.route
API domain coverage
Web pages, identity verification, static assets and APIs may use different domains. Proxying only the main site often leaves the page shell loaded while the login button, model list or response content fails to load. In rule-based mode, confirm that all related requests use the intended route.
Tool × route requirements
The table highlights route-selection priorities; it does not mean third-party tools offer identical features in every region or account state. Check each tool’s official documentation for current availability.
| Tool | Key network characteristics | Desired route performance | Check first |
|---|---|---|---|
| ChatGPT | Web sessions, streaming replies, files and resource requests run together | Stable region, smooth continuous transmission and one path for related domains | Login redirects, model lists and interrupted replies |
| Claude | Frequent long-form output with sensitivity to session continuity | Keep the exit location consistent and prevent local rules from closing persistent connections early | Verification loops, stopped long replies and attachment requests |
| Gemini | Account services, app pages and static assets are interdependent | Use one region for account login and tool pages, with complete resource-domain coverage | Account region, blank pages and missing feature entry points |
| Copilot | Web pages, editor extensions and code-hosting services may issue requests at the same time | The IDE process inherits the correct proxy, while authentication and extension requests remain connected | Extension login, completion timeouts and process proxy settings |
| Midjourney | Interactive pages, account authorization and media-resource requests work together | Do not switch routes during authorization, and keep media-resource paths fully covered | Authorization redirects, image loading and session state |
| Cursor | The editor makes persistent requests and may access model and update services at once | The desktop process can read the system or app proxy, with stable continuous output | Login windows, code completion and missing rules |
The web, desktop and API versions of one tool do not necessarily share the same network path. If the web app works but a plugin fails, check the plugin process and API domains instead of assuming the account is at fault.
Account access: minimize exit changes
The identity-verification flow is most vulnerable when split across different network environments. Fix the route first, then address browser state.
Start with a clean session
If the page keeps returning to the login screen, close the relevant tabs, clear that site’s cookies and cache, then reopen it with a fixed region supported by the tool. Do not change regions on verification pages, authorization pages or during redirects. Browser extensions, custom DNS and split-routing rules may also send some requests outside the intended route, so check them one by one.
VPN PY registration requires only a username and password; no email address is required. After creating a VPN PY account, choose a plan in the user panel and obtain the client and subscription. This service account is separate from any third-party AI tool account. Follow each tool’s official pages for account requirements, regional availability and usage rules.
Separate account issues from network issues
Reaching the tool’s homepage only confirms that basic web requests arrived. If features are missing after login, the cause may be the account region, account status, browser storage or resource domains bypassing the proxy. First compare the page while signed out, then check the difference after login. If browsers behave differently on the same route, inspect browser settings before switching routes again.
Web access and API calls use different paths
Web apps emphasize login state and resource loading. APIs depend more on the interface exit, request duration, certificate chain and whether the running process actually reads the proxy settings.
Web and desktop apps
A web app typically includes the main document, scripts, static assets, identity verification and streaming replies. Global mode is useful for quickly checking whether a rule is missing; once confirmed, organize split routing by domain. For desktop apps, also check whether they use the system proxy, an in-app proxy or their own network stack.
- Blank page: check script and static-resource requests.
- Login redirect fails: check authorization domains and cookies.
- Reply stops: check persistent connections and sleep-related network changes.
API and automated requests
An API client may not inherit the browser proxy. Terminal tools, runtimes, containers and remote development environments each have their own network context. Confirm where the request actually originates, then check environment variables, app parameters, certificate trust and timeout policies separately.
- Connection timeout: check the process exit and proxy variables.
- Handshake failure: check the certificate chain and intermediary proxies.
- Streaming content is truncated: check client reads and connection persistence.
Configuration essentials for CLI tools, IDE plugins and CI
For developer workflows, the key question is not whether the system is connected, but whether the process making the request uses the correct exit.
shell.env
Command line
Network tools in a terminal may read proxy environment variables or rely on application-specific parameters. After changing environment variables, already running terminal processes usually do not refresh automatically; reopen the session and confirm that the current process reads the variables. If the CLI fails while the browser works, check the process environment and certificate trust first.
HTTPS_PROXY / HTTP_PROXY / NO_PROXY
ide.extension
IDE plugins
Copilot, Cursor and other AI coding plugins may send requests from the editor process, an extension host or a separate login window. If completion still fails with the system proxy enabled, inspect the editor’s network settings, extension logs and login redirect. In remote development mode, also confirm whether requests originate locally or remotely.
editor → extension host → endpoint
ci.runner
CI and automated tasks
CI tasks run in an independent runner, so a local computer’s route settings are not passed through automatically. Configure an allowed network exit in the runner environment and inject API credentials through secret management. Automation should also distinguish connection errors, API rate limits, permission errors and the application’s own retries instead of treating every failure as a routing issue.
runner → route policy → API
Common failure symptoms and causes
Record which layer the symptom appears in before changing routes. Frequent switching without a diagnostic sequence only adds more session variables.
The official site opens, but the content area is blank
Common causes include scripts, static assets or API domains not following the same rule, or a browser extension blocking required requests. Check for resource-loading errors first, then compare with a global route.
The verification page keeps reappearing after login
Check whether the exit region changed during authorization, whether cookies are restricted and whether the identity-verification domain bypassed the proxy. Fix the route and create a new browser session; this is usually easier to diagnose than repeated refreshes.
Short prompts work, but long replies stop midway
This is more likely a persistent-connection issue. Check device sleep, network changes, client rules, connection persistence and the local gateway state. If regenerated replies stop at different points, investigate the path before the content itself.
The browser works, but the IDE has no completions
The web path is available, but the extension process may not have inherited the proxy or the required extension domains may be outside the rules. Check the editor proxy settings, extension-host logs and authentication status, and confirm whether requests originate locally or remotely.
The API returns a permission or region message
First distinguish a network response from an API business response. Receiving a clear error usually means the request reached the server. Next verify account permissions, API configuration, exit region and third-party service rules instead of blindly adding retries.
Text works, but images or attachments fail
Media, uploads and downloads may use separate resource domains. Check that these domains use the intended route, that browser policies are not blocking requests and that the current tool account has the relevant feature.
Choose routes by task, not distance alone
A suitable region, stable session and complete domain coverage deserve more attention than the speed of opening a page once.
browser
Web chat
Choose a region supported by the tool and fix the exit before login. Test page resources first, then test continuous replies.
coding
Code completion
Confirm that the IDE process reads the proxy settings, and keep the authentication page, extension requests and model API connected.
automation
API and CI
Confirm that requests truly originate from the runtime environment, and manage the network exit, key permissions, connection persistence and application retries separately.
VPN PY route-selection workflow
VPN PY covers 90+ countries / 200+ routes. For AI tools, start with the route list to review options by destination region, then use one route for login, web chats and streaming tests. If you switch between desktop and mobile devices, unlimited simultaneous devices can reduce repeated sign-outs.
Monthly plans include ¥9.9/month with 60GB, ¥18/month with 250GB, and ¥28/month with 500GB. Traffic resets monthly on the activation date, and mid-cycle upgrades are prorated by the remaining days. If you prefer to keep traffic for long-term use based on actual consumption, you can also choose traffic packages that remain available until used and never expire. See the plans page for exact tiers and access to purchase.
Payment methods include Alipay / WeChat Pay / USDT, and plans come with a 7-day no-questions-asked refund. For the first setup, start with one clearly defined use case: make the web app stable first, then add the IDE, command line and automated tasks. Check the network exit separately for each new runtime environment to make troubleshooting easier.
