xFinity Live Stream Issues

I am not able to stream xFinity at my house.  I have 3 different Roku devices and the app just keeps restarting.  I have powered down my Roku's, restarted it from their app, removed the xfinity app, reinstalled and logged in again.  Still same issue.  I tried to watch Fox Business from my computer and it is not working either.  I select my provider and entered credentials several times but it keeps going back to the select provider screen.

Help!!
