TOOL REQUIREMENTS
AI Tool and Routing Requirements
JiaVPN covers 100+ countries and 240+ routes. Coverage doesn’t guarantee availability for every AI tool; each service may also evaluate your account, region, exit IP, and usage patterns.
| Tool | What to look for in a route | What to test separately | Restrictions that are easy to confuse |
|---|---|---|---|
| ChatGPT | An exit in a region supported by the service; keep the route stable during conversations | Sign-in, streaming responses, and file uploads; test the API separately | Web account benefits don’t include API credits |
| Claude | Check the product’s supported regions and avoid frequently changing exit locations | Account verification, long responses, and file handling | Region notices may also relate to account status and risk controls |
| Gemini | Consider both the network exit and your Google account’s regional requirements | Web features, developer APIs, and access to the relevant models | Availability requirements may differ across product entry points |
| Copilot | Keep the route consistent during sign-in and use; confirm the specific product entry point | Web app, productivity app, or GitHub editor extension | Products with the same name may have different accounts, licenses, and organization policies |
| Midjourney | Keep both task submission and image loading connected | Web app; if using Discord, check its sign-in and asset domains | A failed image load doesn’t necessarily mean the generation task failed |
| Cursor | The editor process can use the intended proxy and sustain responses | Account sign-in, model requests, extensions, and remote development environments | A working browser doesn’t mean requests from the editor use the same route |
Test the entire workflow, not just the homepage
AI chats often return content in chunks over a persistent connection. A homepage mainly loads static assets, while a conversation may use a separate API. File uploads, image downloads, and sign-in checks may also use different domains. To assess a route, complete a real workflow: sign in, send a simple prompt, wait for the response to finish, then test any attachments or images you use. Seeing the page title alone doesn’t mean the tool is working end to end.
IEPL, transit, and direct connections are different types of network paths, not labels for tool permissions. Their performance depends on your local network, time of access, destination service, and current route. A route’s type alone can’t tell you whether it will work well with Claude or provide access to Gemini. Check supported regions first, then test whether your task completes on your network. Once you’ve confirmed a route for work, keep a backup in the same region.
ACCOUNT & SESSION
Account Setup, Sign-In, and Region Checks
Regional availability, account access, and feature availability are separate requirements. Services may change their supported regions and product requirements, so check the official guidance for each product before use. Your exit location is only one factor; account details, organization licenses, billing region, and past sessions may also matter. A network service can’t grant permissions on another platform or guarantee that IP-based risk checks won’t apply.
Keep your exit route stable before signing in
Choose a region that meets the service’s requirements, make sure your client rules are active, then open the official sign-in page. Avoid switching regions or proxy tools repeatedly during account verification. If the page redirects to an external identity provider, check that the new domain also uses the intended route. If the sign-in page loads but submitting the form sends you back to it, the cause may be session cookies, browser extensions, or a failed connection to an authentication domain.
When you see a verification prompt, read the original instructions and follow the platform’s account process. Refreshing repeatedly, resubmitting, or quickly switching between exit routes makes the cause harder to identify. You can use a separate browser profile to rule out extension issues, but clearing a session won’t change your eligibility. Clearing cookies will also sign you out, so make sure you have your account credentials before proceeding.
Keep account requirements separate. JiaVPN uses a username and password and doesn’t require an email address. Account requirements for third-party tools such as ChatGPT and Claude are set by those platforms, not by JiaVPN.
Confirm the specific product, even when names match
Copilot may refer to a web assistant, a feature in a productivity app, or GitHub’s developer assistance service. These aren’t interchangeable: signing in to the web assistant doesn’t confirm that your organization has enabled editor extension licenses. Check the Gemini web app and developer API separately, too. Recording the product name, entry point, and account type helps troubleshooting more than simply saying “AI isn’t working.”
BROWSER ≠ API
How Web and API Connections Differ
Web: browser session
Check authentication redirects, cookies, content APIs, and file assets. Browser extensions can affect requests, while cached content may make the homepage appear to work.
API: the process making the request
Check key permissions, billing status, model access, and request routing. Configure the network for the process or host running the SDK.
APIs and web apps usually have separate authorization flows. Even if you can chat on the web, your developer account may not have billing configured, model access, or available credits. If a request returns an authentication, permission, or quota error, check the relevant settings in the API documentation first rather than assuming the route has failed. Network acceleration doesn’t add paid benefits to a third-party account or change the platform’s API rules.
Streaming requires a stable connection from the client to the destination service. If a regular response completes but a streamed one stops midway, check the app’s read timeout, gateway timeout, reverse-proxy buffering, and whether the local network interrupted the connection. For requests routed through your own gateway, confirm it doesn’t buffer the entire response before sending it. What looks like “no text for ages” may be a buffering setting, not a slow network route.
Test file uploads and image assets separately. If a Midjourney task succeeds but its image doesn’t appear, check the asset domain connection and browser request errors first. If text chats work in ChatGPT or Claude but attachments fail, check file formats, tool-specific restrictions, and the upload path. Don’t repeatedly upload customer data or business documents while troubleshooting; use a test file without sensitive content instead.
TERMINAL / IDE / CI
Request Paths in Development Environments
JiaVPN supports Windows / macOS / iOS / Android / Linux, with no device limit. But a connected client doesn’t mean every app automatically uses the same proxy settings.
Command Line and SDKs: Check Environment Inheritance
Some command-line tools read HTTP_PROXY, HTTPS_PROXY, or ALL_PROXY; some SDKs need a proxy configured separately. Follow the documentation for your tool and use the local proxy address and protocol provided by your client. Don’t copy settings from another device. After changing proxy variables, already-running terminals, background services, and editors may not pick them up. Restart the relevant process, then test the request again.
NO_PROXY and similar bypass settings can also affect results. If a destination domain is on the bypass list, its requests won’t use the proxy; if internal business domains are mistakenly sent through the proxy, internal services may be affected. During troubleshooting, check whether the environment variable is set and whether the destination domain matches its rules. Don’t paste a full list of environment variables containing secrets into a public support forum.
IDE and Remote Development: Check Where the Work Runs
The sign-in window for Cursor or Copilot may open in a browser, while model requests come from the editor or extension process. First check that the editor’s proxy settings work with your client, then review the extension logs. With remote development, code execution, extensions, and model requests may run on a remote host. Routing your local browser through a service doesn’t mean the remote host’s exit route has changed.
A loopback address inside a container points to the container itself, not the host. Pasting the host’s address into a container may result in a connection refusal. Configure a proxy endpoint the container can reach based on its network setup, and restrict access to it. Don’t expose a local proxy to untrusted networks just to troubleshoot. Organization-managed devices should also follow company network and certificate policies.
CI: Configure the Runner, Not Your Personal Computer
When CI jobs run on remote or self-hosted runners, their network exit is determined by the runner environment. The JiaVPN client on your personal computer won’t automatically apply to remote jobs. Check the runner’s network, the destination service’s supported regions, and your organization’s access policies. Use managed secret storage; never put API keys in repositories, build artifacts, or logs.
Automation also needs sensible timeouts, cancellation, and retry handling. Resending an entire task after a streaming response is interrupted may run it twice or trigger extra API calls. Whether it’s safe to retry depends on the API’s behavior. Test logs need only include the error category, request stage, and redacted trace details. Don’t log full conversations, subscription URLs, or credentials.
FAILURE PATTERNS
Common Issues and Troubleshooting Steps
Classify the symptom before changing settings. Change one variable at a time and repeat the same test to avoid masking one issue with another.
The homepage loads, but a prompt hangs. What should I check first?
First determine whether the request wasn’t sent, the API connection failed, or the streaming response was interrupted. Check the error category in your browser’s developer tools or app logs, confirm the content API uses the intended route, then review local rules and app timeouts. A cached homepage doesn’t prove the chat API is working. If testing a backup route in the same region, keep the test prompt and app settings unchanged.
The service says my region isn’t supported. Will changing routes fix it?
Not necessarily. The exit location, account requirements, supported regions for the specific product, and platform risk checks may all affect the result. Check the official supported regions and error details first, then confirm which exit the request actually uses. Account eligibility or organization restrictions must be handled with the service; a network route can’t replace account authorization.
My browser works, but a Cursor or Copilot extension fails. What should I do?
Check whether the failed request came from a local extension or a remote process, then review that process’s proxy settings, environment variables, and certificate errors. Successful sign-in only confirms that authentication worked; model APIs may still depend on organization licenses or request routing. Restart the relevant process before testing again. Reopening the browser alone won’t update the editor’s environment.
The API returns a permissions or quota error. Is it a network issue?
If the server returned a clear permissions or quota message, first check the project associated with the key, model access, and billing status. Connection timeouts, DNS failures, TLS errors, and server-side permission denials are different issues. Don’t attribute every error to the network, and never share keys or full request headers while troubleshooting.
My Midjourney task was submitted, but the image won’t load. What should I do?
Check the task status first, then see whether the image asset request failed. If you use Discord, distinguish between the Discord session, task interaction, and image access. Browser cache, asset domain rules, your local network, and the service itself can all cause similar symptoms. Don’t resubmit a task just because the image appears blank.
How do I send a useful connectivity report?
Include the tool name, client platform, selected region, route type, stage where the error occurred, and a redacted error message. Note whether the web app and API behave differently and whether the issue occurs only in a remote environment. Submit a ticket through the JiaVPN user panel. Don’t include your password, full subscription URL, API key, or business documents.
ROUTE & TRAFFIC
Choose a Route and Plan for Your Workflow
Choose a region based on availability and a route based on task completion. Check the destination product’s official requirements to determine the region, then choose a suitable route from those available in your panel. Test a complete everyday workflow—such as a full response, file upload, or image load—and keep your usual exit location reasonably stable once it works. For a backup, prefer a route in the same region to help distinguish routing issues from changes in regional requirements.
JiaVPN’s route list shows coverage and route types; it doesn’t mean every AI tool feature is available. Policies, account status, and model availability for ChatGPT, Claude, Gemini, Copilot, Midjourney, and Cursor may change. If you still see a permissions error after confirming the network connection, check the destination service’s account and product documentation rather than treating a route change as a universal fix.
Choose a plan based on your actual data usage. Text chats, attachments, image assets, and downloads in development environments all use different amounts of data; chat counts don’t translate directly into data usage. Monthly plans: ¥9.9/month for 60GB, ¥18/month for 250GB, and ¥28/month for 500GB. Data resets monthly on the activation date; mid-cycle upgrades are prorated based on the remaining days.
For occasional use, consider a data package: ¥158/300GB, ¥358/1000GB, or ¥658/3000GB. Data is used as needed and never expires. JiaVPN accepts Alipay / WeChat Pay / USDT and offers a 30-day money-back guarantee. Plan data is separate from third-party AI memberships, model credits, and API fees; it doesn’t include benefits from third-party services.
