ROUTE MATRIX
Tools × Route Requirements
Tools with similar names can work very differently. Web chat depends on login sessions and streaming output, image generation keeps sending task updates, while IDEs and command-line tools depend on whether the proxy covers the relevant processes.
| Tool | Key Network Requirements | Route Features to Prioritize | Common Failure Signs |
|---|---|---|---|
| ChatGPT | Region checks, login sessions, streaming output | Clear exit region with the same path maintained throughout the session | The page opens but messages cannot be sent; responses stop midway |
| Claude | Region policy, stable exit IP, long-form streaming | Avoid frequent exit changes during a session | Returned to verification after login; long responses end early |
| Gemini | Account region, web resource loading, persistent sessions | Use the same exit for page resources and API requests | Incomplete interface; no response for a long time after sending |
| Copilot | Account service, editor extension, background requests | Proxy covers both the browser and editor processes | Web login works, but the editor extension remains offline |
| Midjourney | Login redirects, task submission, image transfers | Keep the region and exit consistent before and after authentication redirects | Authorization loop; task status or images fail to load completely |
| Cursor | IDE login, code context uploads, streaming completions | Stable persistent connections covering desktop application processes | Completions retry repeatedly; chat output stops suddenly |
CONNECTION SIGNALS
Identify Network Requirements First
One session needs a consistent network identity
AI tools often assess the exit region, account region, browser session, and request origin together. Using one route to log in and switching to another region afterward can trigger reauthentication, invalidate the session, or change available features. When this happens, fix a route for the target region, close old pages completely, and establish a new session.
A stable exit does not mean using one specific address forever. It means avoiding frequent changes to region and path during the same login, authorization, or conversation. If the browser, desktop client, and IDE extension use different proxies, their request origins become inconsistent. Check that these processes follow the same network rules.
Streaming answers differ from ordinary page loading. A page opening only shows that static resources can be retrieved; continuous generation requires the connection to stay available for longer. Answers ending mid-generation, code completions retrying repeatedly, and image task updates stopping all point more toward a persistent-connection issue than a basic page-access problem.
ACCOUNT FLOW
Registration & Login
Authentication is most sensitive to network changes midway through the process. Set the region first, then complete the redirect and authorization flow; this is easier to diagnose than repeatedly refreshing.
Fix the Target Region First
Connect to the region you plan to use long term before opening the tool. When clearing an old session, handle the login state for that site only rather than changing several browser settings at once. The login, authorization, and final tool pages should use the same route whenever possible.
Complete the Authorization Redirect
Some tools redirect between account services and product pages. If proxy rules cover only the product domain and not authentication requests, the login page may keep reappearing. Check split-routing rules instead of repeatedly changing accounts.
Confirm the Session Is Established
After entering the tool, make a normal request and check whether output continues arriving. If short content works but long content frequently stops, inspect persistent connections, browser extensions, and system proxy coverage rather than blaming every issue on the account.
WEB / API
Check Web and API Separately
The web app depends on browser cookies, scripts, authentication redirects, and streaming responses. A loaded homepage does not guarantee that chat requests will succeed; a message that sends does not guarantee that a long response will finish. Note whether the failure occurs before login, when sending, or during generation.
- Confirm that the browser itself is covered by the proxy.
- Confirm that the authentication and product pages use the same exit.
- Temporarily disable browser extensions that may rewrite requests.
- After changing routes, establish a new session instead of reusing a problematic page.
API requests usually come from scripts, terminals, service processes, or developer tools and may not inherit the browser proxy. If the web app works but the API times out, first check proxy variables, request-library settings, the DNS path, and the certificate environment of the running process. Do not judge the API route by the browser result alone.
- Confirm that the running process actually reads the proxy configuration.
- Check whether requests are being split onto a local direct-connection path.
- Verify the API endpoint and regional policies provided by the tool’s official documentation.
- Record authentication errors separately from network timeouts.
Browser works + terminal fails
→ Check whether the terminal process reads the system proxy
Web chat works + IDE extension fails
→ Check whether desktop and extension requests are covered by the proxy
Short answers work + long answers stop
→ Check persistent connections, route changes, and sleep settingsDEVELOPER PATH
CLI, IDEs & CI
Developer-environment issues are often not on the tool page itself, but in which process sends the request and which layer controls its configuration.
Command Line
A terminal program may read the system proxy or only the environment configuration of the current shell. First determine which approach the request tool and runtime use, then check whether child processes inherit the configuration. A graphical client being connected does not mean a newly opened terminal will automatically use the same path.
When a request times out, record the destination, error type, and stage at the same time. DNS failures, connection failures, rejected authentication, and interrupted responses have different causes; describing all of them as “the API does not work” removes useful direction from troubleshooting.
IDE Extensions
Development tools such as Cursor and Copilot may send requests through the main application, an extension host, and an embedded browser. Covering only the regular browser with the proxy does not include these background processes. Check that the app’s network options, system proxy mode, and split-routing rules are consistent.
If the extension shows as signed in but completions keep retrying, leave the account and route unchanged first, then inspect persistent connections and background processes. Repeated sign-outs, reauthorization, and region changes add variables and make the original failure harder to isolate.
CI Environment
CI jobs run in an isolated environment and do not inherit the connection state of a personal computer. Check the exit region, proxy variables, DNS, and dependency-download path from the execution environment itself. If different runners handle the job, also avoid switching regions repeatedly within one workflow.
Handle credentials and network issues separately. For authentication failures, verify permissions and variable injection; investigate routes only for connection timeouts. Never print complete credentials in logs; retain only the error category, request stage, and target service.
FAILURE MAP
Trace the Cause from the Symptom
The Page Will Not Open at All
First confirm that the browser is covered by the proxy, then check the target region of the current route. If other international sites work but a specific tool does not, continue checking its regional policy and account status instead of assuming the problem is speed.
The Page Opens, but Messages Will Not Send
Static resources have loaded, but API requests may not be using the same path. Check browser extensions, split-routing rules, and the authentication session. After changing routes, reopen the page so an old connection does not continue using the previous exit.
Output Always Stops Midway
This is more consistent with an unstable persistent connection, device sleep, or a network change. Fix the route, keep the app in the foreground for one test, then rule out local power-saving settings and browser extensions.
The Web App Works, but the Extension Is Offline
The browser and desktop app may use different network paths. Check whether the IDE’s main process, extension host, and background processes are covered by the proxy, and confirm that the app has loaded the latest configuration after restarting.
Returned to the Verification Page After Login
A common cause is a change in exit region before and after the authentication redirect, or authentication requests that bypass the proxy. Keep the route unchanged, close old tabs, and restart authentication from the tool’s official entry point.
The API Returns an Authentication Error
An authentication error does not necessarily indicate a route problem. First verify permissions, key status, request URL, and official policies; investigate the network path only if you see DNS failures, connection timeouts, or interrupted responses.
ROUTE DECISION
Route Selection Order
Choose routes based not on which one is fastest, but on the region the tool allows, the access method, and the connection type.
Choose a Supported Region First
Use the tool’s official policy to determine the target region. Keep the region consistent across login, authorization, web use, and developer calls whenever possible, avoiding repeated cross-region changes within one session.
Then Confirm Proxy Coverage
Covering only the browser is not enough for web chat. Authentication services, desktop clients, IDE extensions, command-line tools, and CI may send requests from different processes, so check each actual access path.
Finally, Watch the Persistent Connection
Do not judge a route only by whether the homepage opens. After signing in, make a normal chat or developer request and watch whether streaming output stays continuous before deciding to change the region or route type.
