Does this stop you from using Cursor

Yes - Cursor is unusable

Hi Dharani,

Thank you for reporting this with the error details.

Based on what we can see, it looks like this was a temporary authentication issue where the desktop app lost its login session. It appears to have resolved itself – are you still experiencing the issue, or are things working for you now?

If the issue does come back, here are the most effective steps to resolve it:

1. Full sign-out and cache clear:

   • In Cursor, click the gear icon (top-right) and select Sign Out

   • Fully quit Cursor (check Activity Monitor to make sure no Cursor processes are still running)

   • Delete the folder ~/Library/Application Support/Cursor

   • Reopen Cursor and sign in via SSO again

2. Check your system clock: Make sure your Mac’s date and time are set to automatic (System Settings > General > Date & Time > Set date and time automatically).

3. Try toggling HTTP/2: Go to Cursor Settings > Network and try enabling Disable HTTP/2. Some corporate network configurations can interfere with the authentication flow.

If it keeps recurring, since you’re on an Enterprise plan, reaching out to [email protected] will get you faster, account-specific support.

Best,
Mohit
