Hey @vicky111,

This isn’t from the API keys you added. We’ve had some slowness on our side over the last few hours that shows up exactly like this, and we’ve let the team know. Give it a little while and start a fresh chat.

If it’s still flaky, switching to HTTP/1.1 usually helps on networks like yours:

1. Cursor Settings (Ctrl+Shift+J) > Network
2. Set HTTP Compatibility Mode to HTTP/1.1
3. Fully close and reopen Cursor, then start a new chat

If it still fails after that, send a real Request ID (click the “…” on the failed message > Copy Request ID) and I’ll dig in.

mohitjain Same here, same problem—switching to HTTP/1.1 doesn’t help.
