Hey, thanks for the report.
The diagnostics show an HTTP/2 protocol error. I see you mentioned trying HTTP 1.1 and 1.0, but in the screenshot HTTP/2 is still selected. Can you confirm:
- Switch to HTTP/1.1 or HTTP/1.0
- Are you using a VPN, proxy, or any network filtering (corporate firewall, Zscaler, etc.)?
- Can you try a different network (mobile hotspot)?
- Please send the errors from Help → Toggle Developer Tools → Console tab
Also try without extensions: cursor --disable-extensions
