User aborted request. Tool call ended before result was received

Support Bug Reports

Hey, thanks for the report.

Let’s quickly check a few things:

  1. Settings > search “HTTP/2” > enable “Disable HTTP/2”, then restart Cursor
  2. Run in terminal: cursor --disable-extensions, a new window will open, then test the Agent. If it helps, remove the problematic extensions one by one. Working fix here: SLOW or NO response from the agent
  3. Settings > Network > Run Diagnostics - send a screenshot
  4. Create a new chat and repeat the request
  5. If you have MCP servers, VPN/proxy, or Zscaler/CrowdStrike, turn them off and test again

If the error persists, please share:

  • 2-3 recent Request IDs right after the error
  • Which tool fails and the exact steps
  • Explicitly pick a model instead of Auto and list which models reproduce it
  • Output from Help > Toggle Developer Tools > Console (red errors)
  • List of installed extensions

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