400 Bad Request

Hi all. I'm having a real problem here and could really use some help. Every time I try to access Unity Learn I'm hit with '400 Bad Request' and the website won't let me sign in to my account. I've cleared cache and cookies until I'm blue in the face. Can someone please tell me how to make 400 Bad Request go away?

I'm having the same issue, it worked fine yesterday

theres an issue with the login system, it may have rando effects on things

Seems to work again now
