Not hosting on one Android device

[Shifty Geezer]

Anyone have experience of hosts not running on some devices? I can launch a host on my Nexus 7 fine, even the S3 Mini, but on the Galaxy Note 10.1 the host isn't detected by other machines (0 hosts discovered).

Assuming you mean LAN discovery, this is done by sending UDP broadcasts to the LAN. It won't work via carrier data as it doesn't allow UDP. TCP is just a much more reliable choice when it comes to mobile device support anyway.

A follow up. Still had this issue with a Wifi LAN game. On a lot of devices, a hosted server is undiscoverable to other devices. Just tried TNet.UdpProtocol.useMulticasting = true; and it makes the server discoverable.

Is there any reason not to use multicasting? Could it not be enabled by default?

I had issues with multicasting on the iOS back in 2014. That's why I defaulted it to 'false' on that platform. Are you saying it works fine now?
