SBG6782-AC got a firmware update yesterday, can't load web interface

Looks like my (purchased) SBG6782-AC got a firmware pushed to it about 24 hours ago.  Since then, the modem has internet, but I can't access the web interface.  Chrome complains about a certificate and won't load it at all, Safari can get past that but then only loads a tiny amount of the page and stops.  I see the copyright is now 2021 so I know it got some sort of update.

Anyone else with this modem get an update recently?
