Hey, thanks for the report. I can see you already tried switching HTTP/2 → HTTP/1.1 → HTTP/1.0, and it didn’t help.
Try this workaround. It helped another user with the exact same stack trace earlier today:
- Rename the project folder in File Explorer (for example
MyProject→MyProject_v2) - Reopen it in Cursor
This resets a corrupted local index. Here’s a resolved thread with the same stack trace: Connection Error / Stalled Agent requests for hours - #9 by Fares_Bendhiab.
If it still doesn’t help, please share:
- Network Diagnostics: Cursor Settings > Network > Run Diagnostics (screenshot)
- Console errors: Help > Toggle Developer Tools > Console (screenshot if you see any red errors)
- Are you using a corporate VPN or firewall (Zscaler, McAfee, etc.)?
- Your ISP and approximate location?
The team is aware of this issue. Over the past couple of days, a few users reported the same stack trace. The diagnostics will help us find the root cause.
Let me know how it goes.
