Hi, @jme60
Thanks for posting, and welcome to the Roku Community.
We're sorry to hear about the issue you encountered with the Xfinity Stream app and acknowledge your efforts to resolve it.
For this matter, we would recommend working with Xfinity support since the specific error code is directly generated by the Xfinity app, which suggests connecting the Roku device to your Home network.
For more information, you can visit Xfinity's article on this specific issue at TVAPP-00101 — Xfinity Stream error code
We hope that this will be sorted out soon.
Best wishes,
Kash
