Thanks for the reply. I don't use a rented modem, the Motorola SB6121 I use is my own. I have rebooted all aspects of my hardware system multiple times. This has never worked on my home network.

I am on my home wifi network, I have a Motorola SB6121 and Google Wifi. Internet works fine, I can stream live TV and any show not marked "in-home".
When I try to watch anything maked "in-home" I get the message "Connect to in-home WiFi to watch". I've seen this on my iPad and Desktop computer both of which are connected to the wifi. I've rebooted devices, reinstalled the app, relaunched browsers all many times. If I open a browser on the iPad and navigate to xfinitiy.com/stream I see the shows without the message, but it wants to open the app to play them. When I open the app I get a message "Looks like you're not on your in-home WiFi" and towards the bottom it even says in small font "Out of home: <wifi icon> <my wifi ssid>". So it knows I'm on WiFi it just doesn't think this WiFi is in my home.
Any ideas? I'm at a loss at this point. I did download the myaccount app, it shows the Cable Modem with a red dot next to it and it says "not connected", though the model number (JRSB6121) looks correct and the Serial number/ mac address matches what's printed on the modem. I configured my Google wifi to use "ISP's DNS" at the suggestion of an internet post. I also followed all the steps here: https://www.xfinity.com/support/articles/xfinity-tv-app-unable-to-connect
I don't know what else to check.
