Security issue warning when logging in

Since yesterday the login page has warned me that the connection is insecure. Has the security certificate expired?

No, everything is the same as it always has been. On my end, I've not had any such issue come up.

Nothing changed for me either

I changed my password and tried logging in using another browser but it's the same. It's just this website. Well, maybe it's not anything serious .

Had that problem with Firefox browser (USA). Seems Firefox doesn't have a renewed security certificate with PF. There is a symbol next to the address bar, a padlock sign with a red bar crossed over it, meaning no security for log-in. Nothing to do with your internet security program.

Had to switch to another browser that has a PF's security certificate and log-in was secure this time.

Seems like it has been fixed, cool!
