Xfinity Stream Apple TV incorrectly says I am not on home WiFi

Xfinity Stream on my Apple TV does not recognize my Xfinity home WiFi correctly.

My Apple TV is connected to my home Xfinity WiFi network. The Xfinity Stream app on my iPad, connected to exactly the same WiFi network, works correctly.

On Apple TV, if I select the “Available out of home” filter, those channels play. If I remove that filter, my correct local Vero Beach channel lineup appears, but those channels say “Available on home WiFi only.”

I have already:

• Signed out and back in.
• Deleted the Xfinity Stream app completely.
• Restarted the Apple TV.
• Reinstalled a fresh copy of Xfinity Stream.
• Signed in again while connected to the home Xfinity WiFi.

The problem remains. The iPad continues to work normally on the same WiFi.

Please escalate this as an Apple TV/tvOS Xfinity Stream home-network detection problem rather than sending me through the standard WiFi troubleshooting again.
