REQUEST PATH
First identify where the AI request fails
The same “won’t open” or “no response” symptom can come from entirely different points in the chain. Identify the failed stage first, then change the route or configuration to avoid switching exits without addressing the real issue.
The page has not loaded
When the browser remains on a blank page, verification screen, or loading state, first check whether the current route covers the target service’s region, then confirm that the system proxy actually applies to this browser. If other international sites work but the target tool does not, focus on region checks, cache, and login state.
Repeatedly signed out after login
Frequently switching countries during login can expose different exits to the account session. Close the relevant pages, choose a route with a clearly defined exit region, clear the old session for that site, and complete the login flow from the entry point without changing routes during verification.
Output stops midway
The page loads, but a long answer disconnects while being generated. This usually points to long-connection stability. Prefer a more stable route, keep the tab on the current exit until the response finishes, and pause browser extensions that rewrite connections or refresh the page.
The web app works, but the API fails
The web app and API may use different processes, proxy settings, and domains. A working browser does not prove that the terminal, IDE, or CI job uses the same route. Check proxy variables, certificate chains, DNS resolution, and request timeouts in each runtime environment.
TOOL MATRIX
Tools × What kind of route they need
The table below describes route-selection priorities, not availability guarantees. Supported regions, account eligibility, and product rules may change, so check each service’s official guidance before use.
| Tool | Key network characteristics | Prioritize | Check first |
|---|---|---|---|
| ChatGPT | Web sessions, streaming text, file transfers | Routes with a stable exit region and steady long-connection performance | Keep the region consistent before and after login; do not switch routes while generating |
| Claude | Long prompts, continuous generation, and attachments | Routes with low jitter and stable session persistence | When long answers stop, distinguish page-session issues from route issues |
| Gemini | Account region, web resources, and ongoing requests | A fixed exit region that matches the account’s usage environment | Whether browser region, account state, and route exit are consistent |
| Copilot | Editor plugins, code completion, and repository context | A route that covers the IDE process and related request domains | Whether the plugin inherits the system proxy and whether the terminal and editor use separate paths |
| Midjourney | Web interaction, asset uploads, and result loading | Routes with stable upload and download performance and fewer exit changes | Troubleshoot upload failures, preview loading, and login sessions separately |
| Cursor | Editor requests, model APIs, and project context | A route suited to continuous requests that covers the editor process | Check for conflicts between built-in, system, and terminal proxy settings |
TOOL NOTES
Connection priorities by tool
Tools with similar names can use very different request patterns. Web chat depends heavily on session persistence, while coding assistants also require the editor, terminal, and plugin to enter the proxy path correctly.
ChatGPT
The ChatGPT web app typically involves page resources, account sessions, streaming responses, and file operations. A loaded page only confirms basic access; if the response stops immediately after generation begins, check whether only the streaming request is failing. Keep the same exit region during login and use, then switch routes after the current conversation is complete.
Claude
Claude is often used for long documents and extended context, so connections typically last longer than simple Q&A sessions. If short prompts work but long answers stop, check long connections, browser sleep behavior, and route jitter first. For attachments, also confirm that browser extensions or local security policies are not blocking upload requests separately.
Gemini
Gemini’s experience may depend on the account region, browser state, and current exit. During troubleshooting, do not check only whether the page opens; confirm that the environment remains consistent before and after login. If changing exits triggers repeated verification, end the old session and re-enter with the selected route instead of repeatedly refreshing the verification page.
Copilot
When Copilot runs inside an editor, its requests may not follow the browser proxy. The editor process, plugin host, login window, and terminal may use different network settings. If browser login succeeds but code completion does not respond, return to the IDE network settings and check whether the plugin reads the system proxy and whether the relevant processes need restarting.
Midjourney
Midjourney involves more than text interaction: it also includes asset uploads, preview loading, and result downloads. If text actions work but uploads fail, do not immediately blame the account. Check the upload path, file requests, and page session separately. Keep the route unchanged while handling larger assets to reduce request rebuilds across different exits.
Cursor
Cursor connects the editor interface, model service, and project-context workflow at the same time. If the chat panel works but code actions fail, check whether the feature uses the built-in connection, system proxy, or a custom model endpoint. Avoid configuring multiple overlapping proxy layers, which can cause duplicate forwarding or partial feature failures.
ACCOUNT SESSION
Keep the environment consistent during sign-up and login
A route controls the access path; account eligibility, regional rules, and product permissions are still determined by each tool. During sign-up or login, the priority is not to search for different exits repeatedly, but to complete the entire flow in a stable, explainable environment.
Choose the region before opening the account page
Before opening the account entry point, confirm that the selected region is within the tool’s currently published service area. Then close old login tabs and start from a fresh page. If the browser has saved a session from another region, clear only that service’s site data so unrelated sign-ins are not lost.
Login redirects often span multiple requests. Changing routes midway can expose different exits to successive requests, triggering extra verification or invalidating the callback. A safer approach is to keep the route unchanged, complete login, enter the product homepage, and only then consider another route in the same region.
Separate route issues from account rules
If the product homepage opens but clearly reports a region, eligibility, subscription, or account-status issue, check the account against the tool’s official rules before refreshing or rapidly switching countries. A network route does not change the account’s regional attributes or replace the authorization process required by the tool.

WEB AND API
The web app and API use different request paths
A working web app with an unreachable API is common. Browsers often read the system proxy automatically, while command-line tools, runtimes, containers, or server jobs may ignore it entirely. Check each process instead of relying only on the browser result.
For the web app, focus on sessions and streaming
- Confirm that browser traffic actually enters the selected route, rather than only some sites being routed through it.
- Keep the exit region consistent during login, verification, conversations, and file uploads.
- When a response stops, first check whether the page is still online, then determine whether the streaming connection was rebuilt.
- After changing routes, establish a new page session so old connections do not continue using the previous exit.
For APIs, focus on the runtime and error type
- Confirm that the application process reads the correct proxy settings, especially for independently launched terminals and background jobs.
- Distinguish connection timeouts, DNS resolution, certificate errors, authentication failures, and quota messages.
- Do not put keys in a script repository; use secure environment variables or the credential-management features provided by the runtime.
- Set a reasonable timeout for long responses, and retry only recoverable network errors.
DEVELOPER FLOW
Configuration tips for CLI tools, IDE plugins, and CI
Developer environments are where “the browser works, but the toolchain does not” appears most often. Each process may inherit proxy settings differently, and containers, remote development machines, and local computers may be on different networks.
Command line
First confirm in the current terminal that requests pass through the route. A terminal opened before the connection was established may not read later system-setting changes, so restart the session. If the project sends requests through a package manager, runtime, or standalone command, check whether that tool supports the system proxy or requires separate configuration.
When a request times out, first use a basic request without real credentials to verify DNS resolution and connection establishment, then return to the full call. This separates network-layer issues from authentication and avoids exposing sensitive information in logs.
IDE plugins
An IDE plugin may run in a separate host process. After changing the proxy, refreshing the editor window may not be enough; close and restart the relevant processes when necessary. In remote development, also confirm whether requests originate from the local interface or the remote workspace. Deploy the route on the side that actually sends the request.
If the plugin login window works but completion fails, check the account authorization callback, plugin request domains, and model API separately instead of assuming they share one connection.
Continuous integration
CI jobs run in independent execution environments and do not automatically inherit the route from a developer’s computer. If the build must call an AI API, design a secure network exit, credential injection, and failure-handling process inside that environment. Keep only necessary status and error categories in logs; do not output complete request headers or key contents.
Automatic retries need clear limits. Region restrictions, authentication failures, and malformed requests will not recover through repetition; retry only brief connection interruptions, timeouts, or cases the server explicitly permits you to retry.
TROUBLESHOOTING
Common failure symptoms and causes
Recording “which entry point, which route, which stage, and what message appeared” is far more useful than writing only “it does not work.” The checks below are ordered by symptom.
The page opens, but no output appears after sending a message
First confirm that the page session is still valid, then see whether the request fails immediately or stops after waiting. Immediate failure points more toward account state, page scripts, or request rules; delayed interruption points more toward long connections and route stability. Keep the current region and reproduce on another route in the same region before switching across regions.
The login page keeps redirecting or asking for verification
Common causes include an old session that does not match the current exit environment or a route change during login. Close the relevant tabs, select a route, clear the site session, and enter again. If the page shows a clear account message, follow the tool’s rules instead of refreshing repeatedly.
Short answers work, but long answers often stop
Check whether the streaming connection stays open, whether the device sleeps, whether the browser freezes background tabs, and whether the route reconnects frequently. Prefer a more stable route in the same region, and let the current answer finish before making other network changes.
The browser works, but the terminal or IDE plugin cannot connect
This usually means different processes are using different proxy paths. Check whether the terminal started before the settings changed, whether the IDE plugin reads the system proxy, and whether a remote workspace sends requests from another device. Restart the relevant process after changes, then verify the connection separately.
The API returns a permission, authentication, or quota message
A clear application-layer response means the request reached the server. Check key status, account permissions, endpoint paths, request format, and the tool’s own rules. Changing routes usually will not alter these results, and repeated retries can make logs harder to read.
The previous region still appears after changing routes
The old page may still hold connections and a session created earlier. Close the relevant tabs, confirm that the system is connected to the new route, and reopen the page. If necessary, clear only the target site’s data instead of resetting the entire browser environment.
ROUTE CHOICE
Choose a route for the task
Distance is not the only factor in route selection. Confirm the tool’s supported regions first, then consider request duration, upload needs, and the device running the task. Throughout the flow, regional consistency is usually more important than frequent switching.
Standard web chat
Choose a region supported by the target tool and prioritize session stability. Use the same exit to open the page, log in, send messages, and receive responses. If the route has issues, finish and clear the current session before switching.
Long text and file tasks
Prioritize long-connection and upload/download stability. When uploading files, generating long answers, or loading extensive context, prevent the device from sleeping and avoid changing system and application proxy settings at the same time.
Code completion and IDE plugins
First confirm that the editor process truly enters the route, then consider changing regions. With a remote workspace, configure the environment that sends the request rather than adjusting only the local browser.
APIs and automated jobs
Handle network, authentication, and business errors in separate layers. The route provides a stable path; keys, permissions, quotas, and request formats belong to application configuration. Retry only recoverable connection issues.
