Login incomplete No Synchronization

Hey, this is a known Linux thing. The browser login finishes fine, but the IDE keeps checking the backend via polling, and the default Electron setting Http: Proxy Support = override can sometimes silently block those requests, so the login looks like it’s stuck.

Try this:

  • Open Cursor, press Ctrl+, for Settings.
  • Search for Http: Proxy Support.
  • Change it from override to on.
  • Restart Cursor and try signing in again.

Let me know if it still doesn’t work. Then we can dig deeper with logs, proxy or VPN, and firewall checks.
