Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Cursor tab stops working after a while. The only way I’ve found to make it start working again is to restart cursor.

This is pretty recent, starting around the time the sign in was introduced.

Steps to Reproduce

Eventually cursor tab stops making suggestions.

Thanks for reporting this! This matches a known issue the team is investigating related to HTTP/2 connectivity affecting Cursor Tab.

Try this workaround (has resolved it for others on Linux):

  1. Open Settings (Ctrl + ,)
  2. Search for “HTTP/2”
  3. Enable “Disable HTTP/2”
  4. Restart Cursor

This should stabilize Tab suggestions. See similar solved case here: Cursor Tab doesn't work

If the issue persists after this, could you please share any console errors? (Ctrl + Shift + P > “Developer: Toggle Developer Tools” > Console tab)

Let me know if this helps!
