Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, this is a generic error and most often it’s a network issue between the client and the model provider. A few steps to debug:

  1. Network Diagnostics: Cursor Settings > Network > Run Diagnostics. Send the result here.
  2. Disable HTTP/2: open App Settings Ctrl+,, search for HTTP/2, and turn on Disable HTTP/2. This often helps on corporate networks, VPNs, or proxies like Zscaler.
  3. If you’re using a VPN or proxy, try turning it off temporarily and test again.
  4. Try a different region or network, like a mobile hotspot, to test. This will show whether the issue is with your local network.

If the error still happens all the time after this, tell me which steps you tried, plus a new Request ID and a screenshot of Network Diagnostics.

I’m having the same issue now for almost 2 hours. Network Diagnostic passes.

@Erik_Madsen, thanks for the Request ID and the diagnostics. Since all checks in Network Diagnostics are green, it’s most likely not a local network issue.

To dig deeper, I’ll need a bit more info:

  1. Which model are you using when it fails auto, GPT-5.5, Claude, etc.?
  2. Your OS and Cursor version Help > About or Settings > About.
  3. Are you using a VPN, proxy, or a corporate network like Zscaler?
  4. Is the issue still happening right now, or did it stop?
  5. If it’s still happening, please share 2 to 3 new Request IDs from different attempts. Privacy Mode should be off, otherwise the details for the request ID are limited.

In parallel, try toggling Disable HTTP/2 in App Settings Ctrl+, then search for HTTP/2, and restart Cursor. Even if diagnostics pass, this sometimes helps with proxy or VPN setups.
