There is definitely a problem and it is with the Viewer side and not the Host side.
No changes to any of my Viewer installations and they are on different internet providers and networks.
Connecting from the Android app works ok.
Connecting on the same network from a previously working desktop computer does not work.

I'm absolutely certain it isn't an issue with the Viewer or Host installation and something isn't communicating or syncing on the Internet-ID servers your side.
