Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

In Agent mode, when i try to ask something. I get after a few moments this:

{“error”:“ERROR_OPENAI”,“details”:{“title”:“Unable to reach the model provider”,“detail”:“We’re having trouble connecting to the model provider. This might be temporary - please try again in a moment.”,“additionalInfo”:{},“buttons”:,“planChoices”:},“isExpected”:false}
ConnectError: [unavailable] Error

This happens quite often, after a few times “Continue and revert” or “Continue without reverting” the agent starts to work.

Steps to Reproduce

Ask in Agent mode something.

Expected Behavior

Agent should start researching or working.

Yes - Cursor is unusable

Hey, are you using an OpenAI API key or a Cursor subscription for the models? If you have the request ID, please share it – that could help investigate. I don’t have direct access to request logs, but staff can view them.

Hey, thanks for the report. Here’s what will help us investigate:

Try network diagnostics:

  • Open Cursor Settings → Network and click “Run Diagnostics”
  • Share the results

Check HTTP/2 settings (especially on corporate networks or with a proxy):

  • Press Ctrl + , to open settings
  • Search for “HTTP/2”
  • Enable the “Disable HTTP/2” option

Test in a new chat: does creating a new Agent thread resolve the issue, or does it persist there too?

Some users report it’s temporary and goes away after starting a new chat, while others see it repeatedly. Understanding your setup will help us decide if deeper investigation is needed.

Thank you!
