Cursor completely unusable - "Provider Error" on all models

Hey, thanks for the report.

I can see the issue started on Feb 5. That same day there was an Anthropic-side service incident that lasted about 6 hours and was resolved. It’s possible the issue is already gone, can you try again?

If the issue is still happening, error 57 plus resource_exhausted is most often related to third-party API key settings. Please try:

  1. Cursor Settings > Models

    • Make sure Override OpenAI Base URL is turned off
    • Temporarily disable your Anthropic API key, just toggle it off, don’t delete it
  2. Fully sign out and sign back in (Cursor Settings > Sign Out, then Sign In)

  3. Try creating a new test chat in a different project

If that doesn’t help, let me know and I’ll share extra diagnostic steps.
