Can't use any model, constant 'Connection failed' error

Hey folks!

I’m running into a pretty frustrating issue and wanted to see if anyone else has experienced this or has any ideas.

Whenever I try to use any model in Cursor, I get the same error message every time:

“Connection failed. If the problem persists, please check your internet connection or VPN.”

I’ve tested pretty much all the available models, and none of them work.
My internet connection is stable, I’m not using any VPN, and I’ve checked my firewall settings, everything looks fine on my end.

Here’s what I’m running:

  • Cursor Version: 0.50.5 (user setup)
  • VSCode Version: 1.96.2
  • OS: Windows 10 Pro (build 26100)
  • Electron: 34.3.4
  • Node.js: 20.18.3
  • Chromium: 132.0.6834.210

And here’s a screenshot of the error:

Thanks in advance! :folded_hands:

Shot in the dark here, but its better than nothing. It has worked to fixed some users’ ‘Generating…’ and similar issues.

Uninstall and reinstall intellicode/intellisense extensions in your Cursor platform. See if that fixes the issue. If it doesn’t downgrade below 0.50x versions and try it again.

Please report back promptly as possible, so we have a continued understanding from any trouble shooting attempts.

Hey! Thanks for the suggestion, I really appreciate the help.

Just an update: I was actually able to solve the issue with the models not loading.
However, I’m now facing a different problem.

Cursor seems to be completely offline at this point. Not even autocomplete is working anymore.
I’m getting this error (screenshot below):

net::ERR_NAME_NOT_RESOLVED
Source: Update Service

I’ve checked my internet and firewall again, and everything is still normal. It feels like Cursor is entirely disconnected, as if nothing can resolve externally.

I’ll go ahead and run some additional tests (like extension reinstalls and possibly a downgrade as you mentioned), and I’ll report back here with any findings.

Thanks again for following up!
