Xfinity Stream for AppleTV bug?: "This device can only access Xfinity Stream on your in-home Xfinity Wifi" error when on home network

So, as I wrote, I AM connected to my "in-home network".  I am in my home, the AppleTV is in my home, and the cable router in my home sees the AppleTV and has provided it an IP address.  Every other app on the AppleTV can access the internet.  

Any other ideas?

Thank you for reaching out and sharing the detailed information about your network setup. We understand how frustrating this experience can be, and we’re here to help clarify.

The error message you're seeing typically occurs when the Apple TV is unable to verify a direct connection to your in-home Xfinity network. While the XB8 modem recognizes your Apple TV through your Orbi mesh network, the current network architecture might be preventing the necessary validation for in-home streaming.

To clarify:

• The Xfinity Stream app on Apple TV does require a direct connection to the in-home Xfinity WiFi network for licensing and content security purposes.
• A wired Ethernet connection from the Apple TV to the XB8 should work, but since the mesh network acts as a bridge, it could be altering the way devices are recognized by the modem.

Potential Solutions to Try:

1. Reconnect Apple TV Directly to XB8 WiFi: Even temporarily, to verify if the error resolves.
2. XB8 MAC Address Check: Ensure your Apple TV's MAC address appears correctly in the modem’s device list.
3. Network Optimization: Ensure the Orbi network isn’t using separate IP addressing, as this could interfere with device recognition.

We understand how important a seamless streaming experience is and are committed to finding a solution. Please let us know if these steps help or if you’d like us to investigate further on our end.

Thanks for the new troubleshooting steps. 

• I tried step 1 on my own.  No fix, noted here in another of my posts in this thread.
• I've now returned to my "standard" configuration, with the mesh network involved (because it's required for my layout).  For Step 2, the XB8 does indeed see the AppleTV, and the MAC addresses match. For what it's worth, the XB8 thinks the AppleTV is connected via ethernet, because the Orbi is in bridge mode.
• For step 3, since the Orbi is in bridge mode, it is not assigning any IP addresses.

Does an Xfinity TV box have to be on the connected at the same time?  I had to disconnect the TV box to connect the XB8 close to the AppleTV, and from what I've read it "should" not be required to use Xfiniity Stream (merely a TV plan), but.....

Great question, no you do not need to have the X1 cable box connected in order to use the Xfinity Streaming app on your Apple TV.
