### Where does the bug appear (feature/product)? Cursor IDE ### Describe the Bug Cursor suddenly looping on the following error. Didn’t use as much as I usually do so I wonder why am I throttled if so?

Hey, thanks for the report. `NGHTTP2_ENHANCE_YOUR_CALM` is usually related to server-side rate limiting, but in your case it looks like a corrupted workspace cache. This is a known issue. Try this in order: 1. Disable HTTP/2 (fastest) Add this to `settings.json` (`Cmd+Shift+P` \> Preferences: Open User Settings JSON): ```json "cursor.general.disableHttp2": true ``` Restart Cursor. 1. If that didn’t help, try the folder rename workaround Rename your project folder in Finder (for example, `MyProject` → `MyProject_v2`) and open it in Cursor. This resets the local index. Downside: you’ll lose chat history for that project, but functionality should come back. Confirmed fix: [Connection Error / Stalled Agent requests for hours - #9 by Fares\_Bendhiab](https://forum.cursor.com/t/connection-error-stalled-agent-requests-for-hours/149395/9) If nothing helps, please share: - A screenshot of Network Diagnostics (Cursor Settings \> Network \> Run Diagnostics) - Console logs (Help \> Toggle Developer Tools \> Console), specifically any red errors when you try to send a message Let me know what worked. ---
