Xfinity stream beta error on Roku

Watched DVR recordings on Roku using Xfinity Stream beta app last night without any problem. Tonight it says "This device can only access Xfinity Stream on your in-home Xfinity Wifi. (Error createDrmSession. 403-102)
I AM on my home wifi. I have restarted my Roku, deleted and reinstalled the Stream app on my Roku and still get the error.

I can use the app with no problem on my phone connected to my home wifi.
