I was away for the weekend, sorry for the delay.
Open your console – did a library fail to load? I have been getting weird errors if, for example, jQuery fails to load. And it’s possible that the certificates are showing as bad on your system, depending on your system clock. If that is far off from the current dateTime, it can often fail on security issues.
My system clock is accurate. Apologies, but I’m not sure about the library loading question. I’m new at this, so I don’t know.

I tried an incognito window with all extensions disabled and anti-virus turned off. Still no luck. I also tried using the “Continue with Email” option, hoping to cut Google out as the issue. No luck. No matter what sign-in method I choose, the results are the same.
I have not yet tried a VPN (I don’t have one) or a different network (I work at home). I did talk to my ISP though, and they say they can’t find a reason at their end for this, if that helps.
Thanks for your help!
