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.
