Forum error cert out of date?

Hi, I’m currently signed in against Chrome’s will. I did a cache wipe of my browser, then I got this when I tried to sign in…

Don’t know why it’s borked for you. LE certs are valid for 90 days (and the “not valid before” is Tuesday, 27 November 2018 at 01:00:14 Central European Standard Time, which ties up perfectly).

It is not the forum, it is the SSO on
That expired today, 22.12.2018 round 5pm, but it seems to be already fixed.

Yes, it’s fine now. Thanks!
