Xfinity Stream on Roku createDrmSession.403-102
I changed plans because "in 2019 my plan was changed to The Grandfather's Plan" and I was advised to go to streaming. OK, fine by me. I bought a bunch of Roku Ultra boxes and put one on each tv (I only use one at a time but I'm a guy so I need one in every room). All are hardwired. I also bought memory for each box as advised. The system worked great. Satified with the performance, I returned all of my X1 equipment. I was using (and continue to use) my own Arris DOCSIS 3.0 modem. 2 days later, all of my Roku are unable to run the Xfinity Stream app. "This device can only access Xfinity Stream on your in-home Xfinity WiFi... error createDrmSession.403-102"
I've seen lots of posts, and appearently people have gotten help, but I've been on the phone every day for 5 days now with no resolution. Can anyone please help me?
