No AI features working. Just hangs indefinitely / no response.

Hey, do you have a Pro subscription? This can also happen if your company uses restrictive software for internet traffic. However, as you mentioned that other staff are fine, it seems that’s not the reason. The cause might also be your antivirus or firewall, so please check that. I also see that you’re using an old version. Is there a reason why you haven’t updated yet?

Cursor has not offered me any updates and as far as I know they’ve not built in any manual way to check for it (at least the button is not in the typical places).

Yes, we have a business subscription.

I have tight control over my system, and while I do have littlesnitch firewall, it is not blocking any comms with Cursor IDE. Disabling it is a simple test already performed.

based on the logs i would think looking up the request ids on cursor end might reveal something useful, even if its just to say the request ids are never making it there.

Today i noticed Cursor Tab status bar was strikethrough, so i clicked to login again, but still nothing is working. Same is true across all projects, local and remote.

Saw these additional errors in the logs, maybe useful.

There was a pending OSX update that I’ve been resisting doing due to the mess it always makes of all the desktops (really i can’t believe they haven’t created an api for per window per desktop memory), after doing the update, Cursor is now working as expected.

Still no notice about any new updates though, about shows same version data.

I’m not really sure why a pending osx update would interfere with cursor’s comms, but it was either that or otherwise a reboot was needed (which again is strange behavior for OS X - par for the course on windoze).

Either way problem solved, maybe it helps someone else in future.
