Where does the bug appear (feature/product)?
Cursor IDE
Describe the Bug
I upgraded to Cursor Pro and the Cursor web dashboard correctly shows my Pro subscription as active. However, every Agent request from the Cursor desktop app fails with an authentication error.
I have already:
signed out of Cursor
fully quit the application
reopened Cursor
signed back in
verified my Pro subscription in the web dashboard
tried a new chat with a trivial Agent request
The error persists.
Request ID:
6a1a10d5-f46b-411e-a79a-90549f7a944c
Backend error:
ERROR_NOT_LOGGED_IN
actionRequired: login
isRetryable: false
Full error detail:
{“error”:“ERROR_NOT_LOGGED_IN”,“details”:{“title”:“Authentication error”,“detail”:“If you are logged in, try logging out and back in.”,“isRetryable”:false,“additionalInfo”:{},“buttons”:,“planChoices”:,“analyticsMetadata”:{“actionRequired”:“login”}},“isExpected”:true}
The Cursor desktop UI appears logged in, while the Agent backend appears to consider the session unauthenticated.
Can you check the account/session on the backend and advise whether the desktop authentication token needs to be reset or the account needs to be refreshed?
I can provide the full stack trace if useful.
Steps to Reproduce
yes
Expected Behavior
i should not be getting the auth error
