A chat runs on a long-lived connection, the answer streams in, and region checks follow your exit IP. The same 90+ countries and 210+ routes apply — but pick the wrong one and the page loads while the answer spins forever. This page breaks down what six common tool types actually need from a network, with a tool-to-route table at the end.
Unlike video streaming, an AI tool runs a request, wait, stream cycle. When any of the three stages breaks, the symptoms look identical: an endless spinner, a dropped stream, or a message that your region isn't supported.
When the page loads, the server uses the location of your exit IP to decide whether to let you in, which version to serve and how to bill you. An exit region that doesn't match where the account normally lives is a common source of "page opens, features missing". Fix the region first instead of switching to a different country on every connection.
A burst of new sessions, sign-ups and logins from a single exit IP tends to trigger human verification. Shared exits run into this more often at peak hours; dedicated routes have cleaner exits. A fixed exit is easier to keep stable than a new region every time you connect.
Answers are pushed as they are generated, and one long reply can run for tens of seconds. Switching routes mid-answer, changing networks or letting the client reconnect throws away what has already been generated and forces a fresh prompt. Long connections care about jitter, not peak bandwidth.
The same route behaves very differently across tools, and the reason is the shape of the requests: one long answer versus hundreds of short completions.
Chats, file uploads and image uploads all happen on one page. When a document with images stalls at the start, it is usually upstream congestion rather than a slow model; keep the same exit for the whole answer, since changing regions mid-session often drops it. An IEPL dedicated line works well here — pin the region to one you use often instead of changing country on every connection.
Long-document reading and writing means large request bodies and long sessions, where packet loss hurts more than raw speed. Loss you would never notice on a short request shows up as repeated stalls in a multi-minute answer. A dedicated line is the safer pick; avoid shared relays at peak hours.
Multimodal, and the page itself is heavy: first paint and images come downstream, and region checks are strict. A relay route works, with the region pinned to one you use often; if first paint is slow, check downstream and DNS resolution before blaming route bandwidth.
In-editor completions fire often and carry little data, so round-trip latency decides the experience, not bandwidth. Jitter matters more than speed: at the same average latency, a jittery route makes completions stutter. Direct or a lightly loaded relay is enough.
The connection has to stay up while the image renders, and the image comes back downstream. Queues can be long, and reconnecting mid-task usually means starting over. Use a relay, and at peak hours switch routes instead of reconnecting to the same node again and again.
Indexing a codebase moves a lot of data for a long time; completions need low latency. The two stages want different things. A dedicated line is best; running indexing and completion work at different times also stops them competing for the same capacity.
Grouped by how you use them, not by how famous the tool is. Route types are explained below the table.
| Tool | Main use | Route requirement | Suggested route type |
|---|---|---|---|
| ChatGPT | Chats, file and image uploads | Enough upstream; exit stays the same for the session | IEPL dedicated line |
| Claude | Long-document reading and writing | Low packet loss, no dropped long answers | IEPL dedicated line |
| Gemini | Multimodal, mixed text and images | Plenty of downstream, fixed region | Relay |
| Copilot | In-editor code completion | Low round-trip latency, low jitter | Direct Relay |
| Midjourney | Image generation and queueing | Connection stays up, stable downstream | Relay |
| Cursor and editor plugins | Codebase indexing and completion | Bandwidth while indexing, latency while completing | IEPL dedicated line |
| CLI and pipelines | Batch calls and build-time requests | Fixed exit, controllable timeouts | IEPL dedicated line |
All routes are grouped by region — 90+ countries, 210+ routes — and you can browse them by region in the route list.
The two steps where risk checks cluster are not in the chat window — they are the first page load and the first login.
Signing up for this service does not need an email address — a username and password is enough. Sign-up requirements on the AI tool side are a separate matter; do not mix the two up.
The same tool, used in a browser or called from code, is picky about different things.
In a browser, same-origin policy, CDNs and region checks all apply. Pages carry a lot of assets, so first paint depends on downstream; answers arrive over a long-lived connection that drops the moment the network changes.
Called from code, timeouts, concurrency and retry policy decide the outcome. Long-context request bodies are far bigger than a normal chat turn, so leave headroom on both upstream and timeouts.
None of these have a browser UI, so when something breaks there is no message to read — you check the configuration item by item.
Most CLI tools read proxy settings from environment variables, so point the proxy at the port your local client listens on. Set both the http and https variables; setting only one often produces the "can pull, cannot push" pattern.
Some follow the system proxy, others have their own proxy setting. When the two disagree, the classic symptom is a browser that works and a plugin that does not. Point the plugin at the same port first, then look at the account and the network.
Build machines usually have no interactive UI and need an exit that stays online. A fixed exit IP is what makes timeouts and retries predictable; inject the subscription URL through environment variables and never commit it to the repository.
Every subscription URL in the examples here is a dummy: https://example.com/sub?token=YOUR_TOKEN. Get the real one from the user panel after logging in, and do not push it to a public repository.
One symptom can have several causes; narrow it down with the table first, then decide whether to change routes or change settings.
| Symptom | Likely cause | What to do |
|---|---|---|
| Page loads but the chat spins forever | The streaming connection was interrupted, or the exit region does not match the account's region | Pin the region, reopen the page, and do not switch routes mid-session |
| "This region is not available" message | The exit IP is registered in a region the service does not cover | Switch to a route in a region you normally use; do not hop between several regions |
| Asked to verify again right after login | The exit IP changed within a short window | Return to the same region you last logged in from and sign in again |
| Image or file upload stalls | Upstream congestion, or a link MTU mismatch | Switch to a route with more upstream, or compress before uploading |
| Plugin works, command line does not | Proxy settings only cover one of the two | Check that the environment variables and the plugin settings point at the same port |
| A long answer stops halfway | Route jitter, or a client timeout set too short | Move to a route with less jitter and raise the client timeout |
You do not need a separate route per tool — four scenario groups cover it.
One IEPL dedicated line in a fixed region is enough; no need to chase newer protocols. Once the region is fixed, both login and chat lose a variable.
A relay route with plenty of downstream. When it stalls at peak hours, switch routes rather than reconnecting to the same node — reconnecting itself interrupts the task.
A dedicated line with a fixed exit, with timeouts and retries configured on the client. Keep long jobs like indexing and builds away from peak hours so a failed rerun does not cost double.
No device limit — one subscription can connect on several devices. For long sessions, use a single exit at a time so the same account is not hopping between regions.
Routes are grouped by region and listed in the route list; monthly plans are ¥9.9/month for 60GB, ¥18/month for 250GB and ¥28/month for 500GB — see the plans page for details.
Most often the streaming connection was interrupted: the route changed mid-session, the device switched between Wi-Fi and mobile data, or the client reconnected. Pin the region, reopen the page and try again; if it still spins, move to a route with less jitter.
Not exactly. Routes differ in exit region and path, so the odds of tripping region checks and human verification differ too. A route that is fine during the day and degrades at peak hours is usually a shared-path load issue — switching routes works better than reconnecting repeatedly.

No. Plans are billed monthly: ¥9.9/month for 60GB, ¥18/month for 250GB and ¥28/month for 500GB. Data resets monthly on your activation date, and upgrading mid-cycle converts the price difference into remaining days. If you run out, you can add a data pack — it is used until it is gone and never expires.
