I have a Tivo Roamio, 2 Tivo Mini Vox, and 2 older model Tivo Minis all running the latest Tivo Experience OS. On the Roamio, 1 Mini Vox and 2 older Minis everything works fine. I go to my shows and can play any content. On the "bad" Mini Vox, I can not play any newly recorded content. When I attempt to, I get an Xfinity screen that says "There is an issue with your Connection. We had and issue while attempting to notify you..........." I can confirm that there is no issue with my connection. The "bad" Mini Vox just won't play content for the very first time. If I go to one of the working Tivos, My Shows, and play the content that generated the message for a few seconds and then go back to the "bad" Mini Vox I am now able to play that show. I can also play a show via the iOS app and that will also allow the "bad" Mini Vox to play that show. I have moved a working Mini to the "bad" Mini Vox network connection - no issues I have moved the "bad" Mini Vox to several of the working Tivo network connections - no change - can't play content for the very first time. I have rebooted as well as successfully connected to Tivo on the "bad" Mini Vox countless times. I have also wiped and re-setup the "bad" Mini Vox - no change in behavior. Comparing the System Settings between the "bad" Mini Vox and the other Tivos, they seem to be identical (as far as I can tell). There seemed to be some threads with similar behavior, but none of the things I've seen have helped my situation. Any help or suggestions are appreciated.
