Can't sign into account - get a 504 gateway timeout

The site has obviously been changed.  I can't get it to get past the entry of my password.  In order to get that far, I had to try to sign into a business account, get refused (I don't have one), then the box to enter ID and PW finally popped up.  While I am using brave, I turned it's security off.  I tried Chrom and it was horribly slow, but I got the box to enter ID then PW, but then it went to never-never land.  What's up?
