Hey, I can see from the screenshot that Network Diagnostics gets stuck on DNS or SSL and shows Timeout waiting for EverythingProvider for several services.
One quick note. The Network Diagnostics UI itself has a known bug where DNS and TLS checks can spin forever with no timeout, so a stuck spinner alone does not prove your network is broken. This issue is being tracked, there is no ETA for a fix yet.
Now the main point. Timeout waiting for EverythingProvider usually means the Extension Host or cursor-socket did not start. From the symptoms, it looks similar to this thread Timeout waiting for EverythingProvider Error. The comments there include a few fixes you can try.
What to try in your case on Windows after a forced reinstall:
- Full reboot of the machine. After reinstall, stale DNS or old network state from the previous process often remains.
- Check Windows Firewall and your AV. Rules may have reset during reinstall and Cursor might be blocked. Temporarily disable AV and test.
- Disable HTTP/2. Open Settings with
Ctrl+Shift+,then search for HTTP/2 and enable Disable HTTP/2. Or add"cursor.general.disableHttp2": trueto settings.json. - DevTools. Help > Toggle Developer Tools > Console tab. Try sending a prompt, then paste the red errors from there. They will show whether the request is failing on network, SSL, or not even being sent.
If none of that helps, please share a Request ID from any failed prompt attempt Cursor Settings > top-right of the chat > Copy Request ID.
