Hey, thanks for the report.
This looks like a known HTTP/2 issue. Please try these steps:
- Settings
Ctrl+,. Search for “HTTP/2”, enable “Disable HTTP/2”, restart Cursor, and test again in a new chat.
- Settings > Network > Run Diagnostics, then send a screenshot of the results.
- Are you using a VPN or proxy, or do you have any MCP servers connected? Please try disabling them.
If the issue persists, please send:
- The Request ID from the error popup (if shown)
- Help > Toggle Developer Tools > Console, plus a screenshot of any errors
Similar resolved reports:

Thanks for the screenshots. I can see timeout errors and “connection reset” when calling api3.cursor.sh.
Have you tried the first step I mentioned above, disabling HTTP/2? That usually fixes it:
- Settings
Ctrl+, > search for “HTTP/2” > enable “Disable HTTP/2” > restart Cursor > test again in a new chat
If it still happens after that, please send:
- A screenshot of the results from Settings > Network > Run Diagnostics
- Whether you’re using a VPN, a proxy, or any MCP servers. If yes, please try disabling them
Same thing is happening to me with same cursor version.
