Hey @Ethan_YY. Thanks for the report and the Request ID, I checked it on our side.
This request streamed normally and had already started a tool call, then messages from your machine stopped reaching our servers. Our servers waited about 10 minutes and then ended the request due to a timeout. Over the last week, Cursor also logged many connections from you that were reset or dropped before finishing, across several Cursor versions. This points to the network path between your machine and our servers, not something inside Cursor itself.
It looks like most of the traffic is going through a VPN or proxy. Please try this:
- Open Cursor Settings > Network > Run Diagnostics and paste the results here.
- If you’re using a VPN or proxy, switch to a different server or node or temporarily disable it, then open a new chat and send a message.
- In Cursor Settings > Network > HTTP Compatibility Mode, select HTTP/1.0. It uses short requests instead of one long connection and usually handles unstable connections better.
- After the changes, restart Cursor and try a fresh chat with the agent.
If it still fails, send a new Request ID and the exact error text from the chat, like “Agent stopped retrying” or “Connection failed”. Let me know how it goes.
Now the cursor is working fine and no longer throwing this error. It might have been due to network or node fluctuations in the past couple of days, or possibly because I set up a reverse proxy within Cursor to use models like GPT.
A couple of days ago, for some reason, my Pro plan’s Cursor model usage suddenly jumped to 40%, going from 3% overnight. I’m not sure if this is normal billing behavior or a bug—could you please help me check?

Glad the errors cleared up. Like you saw, that pattern matched an unstable network or VPN path, not something inside Cursor, so switching nodes or using HTTP/1,0 helps keep those long connections alive.
On the usage request, that’s tied to your account, so our team at [email protected] is the right place to help. Send them a note and they can check the jump in your Cursor model usage.
