Error createDrmSession 403-102

@CCKenF I have my own modem and wifi as well as 3 Roku Streaming Stick+ devices.  Two of the Roku devices are working with the Xfinity Stream App, but one is getting the Error createDrmSession 403-102.  I have called support, removed and reinstalled the app, reset my network connection in the Roku and and reset it back to Factory Defaults and restarted the Roku itself.  I have also restarted my modem and restarted my wifi network.  I cannot get around the error.  Can you help?
