The web app first requires a complete sign-in flow. If the sign-in page opens but the chat keeps loading, check separately whether the authentication domain and chat requests use the same egress. When a long response stops midway, do not judge the route by download speed alone; check whether the connection reconnected or the egress changed during streaming.

API calls usually come from a terminal, backend process, or cloud job and do not share the browser's proxy environment. A working browser session does not mean command-line requests use the same route. Before deployment, determine whether the proxy applies to the current process, the whole system, or only the container.

Claude is more sensitive to consistency between the egress region and the session environment. Switching regions before and after sign-in, or sending browser and system requests through different egress points, can trigger region notices, abnormal authentication responses, or pages stuck loading. For a long-term account, a stable preferred egress is usually better than constantly searching for new routes.

Long-form generation and document processing keep sessions open longer. If short prompts work but long responses often stop, try a route with a more stable topology first, then check browser extensions, sleep settings, and network switching instead of repeatedly submitting the same request.

Gemini's available features may depend on account type, location settings, and service policies. On the network side, sign-in, page resources, and generation requests should all complete through the same route. If the page frame appears but the feature area is blank, first rule out scripts or authentication requests falling outside the proxy scope.

After changing egress, old session data may cause the browser to keep sending region-related cache and cookies from the previous environment. During troubleshooting, change one variable at a time: hold the route steady, establish a fresh session, and then determine whether the issue is network-, account-, or browser-related.

Copilot commonly runs as an editor extension. The extension may use a browser for sign-in, while code-completion requests come from the editor process. If only the browser has a proxy configured, web authentication may succeed while the editor remains offline or keeps retrying. Check whether the editor process inherits the system network settings.

Completion requests are small individually but frequent, making them sensitive to connection recovery and DNS paths. In an office environment, also check whether system proxies and enterprise network policies are both handling the same request, which can create forwarding loops or leave only some domains reachable.

Midjourney involves more than submitting prompts: previews, full-resolution images, and uploaded assets also need to transfer. If the text interface works but images take a long time to appear, media requests may not be following the same proxy route, or the route may reconnect during larger transfers.

When using reference images, reliable uploads matter more than initial loading speed. If the task does not continue after an upload, first verify that the asset was fully sent, then confirm that the web session is still valid. Do not change the egress region while a task is running.

Cursor involves account sign-in, in-editor chat, codebase indexing, and model requests. Different features may be handled by different processes, so the most common issue is incomplete proxy coverage: sign-in works, but indexing or chat waits indefinitely. System-level configuration is generally easier to keep consistent than configuring only the browser.

The integrated terminal may still use its own environment variables. If editor chat works but a terminal script fails, check the terminal session's proxy variables, DNS, and certificate environment separately. Restarting the editor after closing it allows related processes to inherit the new settings completely.
