Unable to login in at all

I am unable to log into my Xfinity, full stop. 

My initial problem was that my NOW Wifi Pass was telling me I had reached my device limit, when I know that wasn't the case. During a live agent chat, they informed me that through my account I could manage the devices connected to the hotspot with my credentials. They gave me the link to the specific website to use. When I tried to use the link and use my Xfinity login credentials to access my devices, I am unable to log in at all. It sends me on an endless loop of logging in, to it saying there is an error to Try Again, and over and over again. 

I even tried simply logging in from the normal Xfinity.com page, and logging into my account there. When I try that, I just get an endless loop of the 3 dots moving in the loading fashion, forever. 

During one of my live chats, I was advised to clear my cache and that that would help my problem. Well, it didn't. I've attempted logging in on Google Chrome (my browser of choice), Safari on my laptop, and even Safari on my phone. Same thing happens everywhere. Loading, loading, loading, and NOTHING!!!!

Speaking to live chat agents couldn't help me. Calling the 1-800 tech number didn't help me. I NEED SOME HELP!!
