Directv.com redirect to AT&T

Has anyone else had this issue or know how to stop it! When I go to Directv.com and try to watch something and it asks me to sign in, I put in my log in information and it automatically redirects me back to my ATT account information page. If I try to go through that page to get to the Watch TV link it takes me right back to square one....It's beyond frustrating at this point!!!!
