From regional detection and consistent egress to persistent streaming connections and developer proxies, this guide explains how ChatGPT, Claude, Gemini, Copilot, Midjourney, and Cursor differ in their network requirements.
A route that opens a regular webpage normally is not necessarily suitable for ongoing conversations, code completion, or API calls. Evaluate the region, egress, connection continuity, and application path separately.
AI platforms often determine available features using the egress IP region, account region, and product availability. Before the first visit, choose a route in a region supported by the target service, then open the website or app. If the page has retained information from an earlier region, close the relevant pages, reconnect, confirm the egress region, and visit again.
Use the same route for the login page, verification page, and main workspace whenever possible. Frequently switching between geographically distant egress points within a short period may trigger additional checks or cause the page to alternate between regional assessments. When changing routes, end the current session before reopening the service entry point rather than switching during submission.
Conversation generation, code completion, and image tasks often rely on persistent connections. Packet loss, egress reconnection, or local sleep may not disconnect the entire webpage; instead, an answer may stop halfway, a cursor may keep waiting, or a plugin may retry repeatedly. In these cases, prioritize a stable route rather than judging only by how quickly the page first opens.
Browsers, desktop apps, command-line tools, and IDE plugins may read different proxy settings. If the webpage works but a plugin does not respond, the app may not be using the same egress rather than the AI service being down. During troubleshooting, identify which program sent the request, which layer of network configuration it reads, and whether DNS resolution follows the same path.
Use the table below to identify route-selection priorities. It does not mean every platform offers the same features in every region, account, or time period. Refer to each platform’s official documentation for current availability and account rules.
| Tool | Primary Network Scenarios | Route Features to Prioritize | Common Symptoms | Where to Start |
|---|---|---|---|---|
| ChatGPT | Web conversations, file interactions, streaming responses, API | Regional match, stable egress throughout the session, continuous persistent connections | Entry point unavailable, interrupted responses, repeated login loop | Check the egress region first, then confirm that the browser and API use the same path |
| Claude | Long-form conversations, document processing, developer calls | Stable egress, persistent sessions, minimal route switching mid-session | Pages repeatedly reload, long responses pause, requests remain pending | Close the old session and re-enter using a fixed route |
| Gemini | Web workspace and related services within the account system | Keep the egress region aligned with the account environment | Different feature entry points, regional notices, returning to the original page after a redirect | Check the account environment, egress region, and browser session |
| Copilot | Web, system services, code assistance inside an IDE | Application-level proxy reachability, consistent authentication and completion request paths | Web access works but the plugin waits, or remains disconnected after authentication | Check how the IDE’s own proxy settings inherit from the system proxy |
| Midjourney | Task submission, asset upload, result delivery | Stable upload and return paths, with no route changes during the session | Asset submission fails, task status does not update, results load incompletely | Check the upload path and keep the egress unchanged throughout the task |
| Cursor | IDE conversations, code completion, project-context requests | The development process can read the proxy, and streaming requests remain stable | No response in the editor, completion requests wait, terminal and IDE behave differently | Verify the network path separately for the IDE, integrated terminal, and external terminal |
Connect to the regional route you plan to use long term before opening the tool’s website or app. If the browser retains an earlier regional session, exit the relevant pages and establish a new connection. This reduces the chance that the login entry, console, and main workspace identify different egress points.
Third-party account authorization may redirect across several pages. Do not switch routes during the redirect, and do not let one page use the proxy while another bypasses it. If authorization still returns to the login page, first check whether every redirect domain uses the same network path.
Keep the egress unchanged during long conversations, document uploads, or image tasks. When switching regions, save the content in progress and end the current task before reopening the workspace through the new route. Switching during generation may invalidate the existing connection while the page still appears unchanged.
If the account requests additional verification, complete the normal checks shown by the platform. Do not repeatedly try multiple regions. The network layer can address reachability, routing, and connection stability; it cannot replace the platform’s own account rules or regional policies.
This service does not require an email address; a username and password are enough to create an account. Before connecting a tool account, use the LeeVPN dashboard to select a route and check the egress.
A browser conversation working normally only proves that the browser’s request path is available. API clients, terminal programs, and automated tasks must be tested separately to confirm whether they use the same route.
Web access is affected by the browser session, cache, account authorization, extensions, and system network settings. If the page is blank, redirects repeatedly, or responses stop, confirm the egress region first, then reopen the target site in a clean session and note whether the issue appears before login or during generation.
API requests are usually sent directly by a script, runtime, or server process and may not inherit browser settings. Check whether the running process reads proxy environment variables, how DNS resolution is routed, the connection timeout policy, and whether an intermediate network closes streaming responses early.
Developer tools often involve several network layers at once: system proxy, application proxy, runtime environment variables, container networking, and remote execution environments. Judge the path where the request actually occurs rather than looking only at the local browser.
Whether a terminal program reads the system proxy depends on the runtime and tool settings. First use the same terminal to verify that the target domain can establish a connection, then run the actual script. If an external terminal works but the IDE’s integrated terminal fails, compare environment variables, launch methods, and network inheritance on both sides.
Keep the original error type during debugging: DNS resolution failure, connection timeout, certificate validation, platform authentication, and request quota are different problems. Do not attribute every error to the route, and do not change multiple configuration items before the cause is clear.
Copilot, Cursor, and other editor tools may use separate processes to establish connections. Even after browser login succeeds, a plugin may remain waiting because its application proxy is not configured. Check the IDE’s network settings, whether the authentication callback completed, and whether plugin requests use the expected egress.
Code completion involves frequent, continuous requests and is more sensitive to brief interruptions. If regular conversations work but completion fails intermittently, keep one stable route and observe instead of switching repeatedly between regions. During project indexing or large-context processing, also prevent the device from entering sleep and interrupting the network.
CI tasks run in remote execution environments. Being connected to LeeVPN locally does not mean the remote task automatically uses the local route. Confirm where the task actually sends requests from, which outbound methods the remote environment permits, and whether keys are managed through the platform’s secure variables.
Automation should also distinguish intermittent network interruptions from code logic errors. Record the platform status, request stage, and failure location, but never print access keys or complete authentication details in build logs. For long-running tasks, use explicit retry and timeout policies and avoid resubmitting the same work unconditionally.
Possible causes: The egress region is outside the service’s availability range, an old session retained information from another region, or the login redirect and workspace use different egress points.
What to do: Close the relevant pages, choose a route matching the region, confirm the egress, and re-enter through the service entry point.
Possible causes: The authorization redirect paths differ, the browser session is abnormal, or switching routes changed the network environment before and after login.
What to do: Keep one route throughout the authorization flow and, if necessary, sign in again with a new browser session.
Possible causes: A persistent connection was interrupted, the local network switched, the device went to sleep, or the route briefly became unstable.
What to do: Keep the device online, use a stable fixed route, re-establish the session, and submit the content again.
Possible causes: The running process is not reading the proxy configuration, DNS resolution is not following the expected path, or the connection timeout does not match the task.
What to do: Test the connection from the environment where the process runs and distinguish a network timeout from a platform error.
Possible causes: The IDE uses separate network settings, the plugin process did not inherit the system proxy, or the authentication callback did not return to the editor.
What to do: Check the IDE’s own settings and test the integrated and external terminals separately.
Possible causes: The upload and page paths differ, the egress changed during the task, or the persistent connection ended early.
What to do: Resubmit using a fixed route and keep the upload, task status, and result retrieval on the same path.
Prefer a stable route in a region where the target tool is available. Keep the same egress during login, conversations, and file handling. When something fails, re-establish the session before deciding whether to change routes.
Beyond regional matching, confirm that the editor process actually uses the route. Continuous completion depends more on connection continuity, so minimize egress changes during work.
Locate the environment where the request actually runs, then configure its network path accordingly. Local connection status does not represent a remote execution environment, and error logs should distinguish network, authentication, and platform rules.
Keep uploads, task submission, and result retrieval on the same path. Switching routes during processing may invalidate the current session, so stability is usually more important than repeatedly seeking a new egress point.
