Not able to stream Space City Home Network while on home network

I am not able to watch Space City Home Network (or any non-TV Go channel) while connected to my home network.

I've tried on an iPad running iPadOS 18.3.2 (22D82) with Stream app version 7.21.1.2781 (d07842fa11).

I have verified I am connected to my home WiFi.

I have verified I have no filters applied.

The "All Channels" list only shows TV GO channels.

I have also tried on my PC with multiple browsers, all without any ad blockers.

Please help to restore access to all channels while at home.
