Xfinity Stream will not cast

I have found numerous posts regarding this issue, but no conclusive fixes. I have had the Xfinity app on my Android phone for sometime with no issues. Once fine day, it simply stopped casting, it says its casting and the Chromecast shows a still screen with the tree dots but never fully connects. SO, I tried installing the app on my iphone, will not cast. Tried from my laptop, from the Xfinity website, will not cast. Installed my brand new Chromecast, still does the samething on all three devices. I can cast from any other app on any of the devices to either of the chromcasts without issue, but not from the Xfinity stream app from any device to either chromecast. 

The only thing I can think of is once the connection is made, the app it's self is blocking the stream from flowing to the cast. It is the only common denominator in my scenario. Now the question becomes why is the app blocking the stream from flowing once the connection is made? AND how do I fix it?
