Connection error in Cursor when on Ukrainian IP

Support Bug Reports
2

Hey, thanks for the report.

Quick workaround to try:

  • App Settings Ctrl+, → search “HTTP/2” → enable “Disable HTTP/2” → restart Cursor → test chat again.

If it still fails, please share:

  • Settings → Network → Run Diagnostics (screenshot)
  • Your ISP and whether you’re using any firewall/proxy (e.g., Zscaler)

Reference: another user hit the same SSL alert and disabling HTTP/2 fixed it: SSLV3_ALERT_HANDSHAKE_FAILURE when creating new chat

Let me know if the HTTP/2 toggle helps.
