(Error TVAPP-00100) Error!!! Xfinity Stream down!!!

All of a sudden I can not use Xfinity Stream!!! :(

I am getting Error (Error TVAPP-00100)

First last week I could not see my DVR Recodings and On Demand was not working on Xfinity Stream which was fixed after a little less then a week. 

And now just a few days later I can't use Xfinity Stream at all because of this error!

What is going on lately at Comcast?????
