Cursor Tab doesn't work

[Alexey_Konyshev]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Cursor Tab stopped working. All the options are on and checked multiple times. When I hit Tab, nothing happens. No network requests in developer tools.

SOMETIMES it can show a suggestion, like once an hour, but this is incomparable with the outcome I had when decided to switch to PRO.

In the attached video it worked after several attempts and made one suggestion. After I accepted it, it stopped again. I was really lucky it worked, usually it doesn’t at all.

Steps to Reproduce

Open cursor IDE with some project, hit Tab or just go to the place with the obvious things to suggest.

Expected Behavior

The suggestion fron cursor tab should show up.

Turned off http2 and it works again

Hey, thanks for the report. Glad disabling HTTP/2 got Cursor Tab working again.

This is a known issue and the team is already investigating it, several users have reported the same. The team is looking into the underlying HTTP/2 connectivity problem.
