AT&T log in screen keeps looping!

Every time I type in my user ID and password it automatically logs me back out. I can’t get into my email and need to for work. I have cleared cash and cookies. I’ve tried to log in from multiple different browsers and devices. I’ve also tried changing my password multiple times. Nothing has worked so far. This has happened to 3 of my family members before and they had to have their accounts resynced. Please help:/
