This is an known issue with some versions of FF.
Maybe a recent update?
I can't get that error here (tried on several browsers)
Okay, Thanks for checking.
I'm pretty sure if that was related to Poal (which isn't - Nothing related to SSL/certs has been recently changed) more users would be reporting that issue.
Librewolf is also known to have cert/ssl issues.
A reboot will probably take care of it. And I'll reset my internet too.
