For AI issues: which model did you use?

Composer 1

For AI issues: add Request ID with privacy disabled

Request ID: bad8d495-2f4d-468d-b9c4-b83a4a72ed98
{“error”:“ERROR_USER_ABORTED_REQUEST”,“details”:{“title”:“User aborted request.”,“detail”:“Tool call ended before result was received”,“isRetryable”:false,“additionalInfo”:{},“buttons”:,“planChoices”:},“isExpected”:true}

Additional Information

  • Cursor keeps showing “Downloading updates,” but there’s no progress
  • I was using a different company account when I encountered the problem, so the requestID I provided also came from that company account.

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report. This issue is affecting a few users. Let’s check a couple things:

  1. Settings > search for “HTTP/2” > enable “Disable HTTP/2”, then restart Cursor
  2. Run this in a terminal: cursor --disable-extensions. A new window will open, test the Agent there. If it helps, disable extensions one by one. More details: SLOW or NO response from the agent
  3. Settings > Network > Run Diagnostics, then send a screenshot of the results
  4. Create a new chat and repeat the request
  5. If you’re using MCP servers, a VPN/proxy, or Zscaler/CrowdStrike, turn them off and test again

About “Downloading updates”, that’s a separate UI issue. Just restart Cursor to reset the UI state.

If the issue still happens, please send:

  • 2 to 3 new Request IDs right after the error
  • Which Agent tool is failing, and the exact repro steps
  • Pick a specific model instead of Auto, and tell us which models reproduce it
  • Output from Help > Toggle Developer Tools > Console (red errors)
  • Your list of installed extensions

Let me know if disabling HTTP/2 or running without extensions helped.

@deanrie Hi Dean, the issue of slow agent code generation has been resolved.

I suspect it was caused by too large context in my session.

Thanks for your assistance!
