Hi @bobcmil,
Thanks for joining us here in the Roku Community!
We see that you're running into an error 500 when trying to access the Xfinity stream channel. It looks like the issue is probably on the channel's server. It seems like the usual troubleshooting steps won't work for this. We'll see if the following steps can help out.
- Disconnect the coax cable from the modem/router
- Power cycle modem/router
- Reconnect coax cable
If this doesn't apply to you, just report the issue to the channel support team for help. Roku only offers the channel on the platform, but we don't manage it directly.
You can contact them here directly at Xfinity support.
Let us know if there's anything else we can further assist you.
Thanks,
Rey
