Yesterday, I viewed the EU and US forums without any trouble. This afternoon though, when trying to access both, I get warnings about the site’s security certificate, as follows…
Using Google Chrome - Version 79.0.3945.117 (Official Build) (64-bit)

The domain’s certificate was valid from 00:00 10th January 2018 to 12:00 15th January 2020, i.e. it expired around 2 hours 15 minutes ago.
Guess you might want to renew your certification.
