Can't access e-mail page.

I created a Cox e-mail, but now when I try to access it, I just get a blank page and the URL endlessly loops:


https://myemail.cox.net/appsuite/

So far I've tried: deleting all cookies, allowing cookies/popups etc. for the cox.com domain.
Tried Google Chrome, Edge and IE (latest versions) but no luck accessing my email yet.

I also successfully added the email account to the mail app on Windows 10, but whenever I try to send test e-mails, I get the undeliverable error from postmaster@cox.com 

Any help would be greatly appreciated.
