Playback issue 1001 error 4

I am unable to watch any "available TV Go" channels or Recordings on my mobile devices (Google Pixel 6 and Amazon Firestick) when I'm away from my home network. I get playback issue 1001 error 4, with Live TV Go channels on both devices, and then "Well that didn't go as planned" again on both devices when trying to watch recordings.  I have cleared cache, uninstalled and reinstalled the Xfinity Stream app with no success.
