Error: We're Having A Problem Something isn't working right. Give it some time and try again. (Error code:652314)

When I log in to my att email account on my laptop today, it goes in circles from the Login.yahoo.com page, where ATT has you enter your email address, to the signin.att.com page, where you again enter your email address, then also enter your password, back to the Login.yahoo.com page to enter your email address, then to the https://www.att.com/my/#/invalid-login-error where is says: We're Having A Problem Something isn't working right. Give it some time and try again. (Error code:652314)

I am logged on to email on my phone so the server must not be down (and I almost always leave that logged in, so don't say that is interfering with logging in on my laptop).  ATT did this a few months ago, and it took over a week until it finally stopped.  I need my email for important communication.
