Error Authenticating on Amazon Fire Stick - DirecTV

I added the Uverse app to my Fire Stick and when I attempt to login I get "error authenticating please try again". This error happens on both my fire stick and fire tv. I can login just fine on the computer but have never been able to access Uverse on the fire stick. My login and password have been checked and rechecked and they are not the issue. What can I do to gain access to Uverse on my Fire Stick?
