Chat and composer instantly fail and reset (unable to use cursor)

[svarlamov]

Steps to reproduce (happens on any workspace, suddenly started today):

1. Open cursor chat/composer
2. Type a message
3. Press enter/click submit
4. Chat appears to start working, but then instantly closes. Errors appear in dev console.

What I’ve tried so far:

1. Quitting/reopening
2. Reinstalling cursor without deleting settings and ~/.cursor
3. Wiped all cursor app data and settings, reinstalled

Since posting:

1. Can’t log in to cursor (and it was asking me to upgrade to pro, but I’ve been a pro user for months and the web-based account pages confirm that I’m a pro user)
2. Cmd+K editing was working intermittently, but has since stopped working since the login issue started.

Is Cursor having an outage right now? I’m can’t log in on a fresh install and seeing certificate errors in the logs + in chrome when I open the URL.

Update: using a VPN appears to have fixed things for me
