Multiplayer Quake1 - Is it supported via Libretro / Lakka / TyrQuake?

Hi Everyone - has anyone managed to get mulltiplayer working in libretro/tyrQuake for Quake1?

There is a [Libretro Twitter announcing support for it here (https://twitter.com/libretro/status/1189274002075930636?lang=en) back in 2019.

I’ve tried a Lakka on a Pi4 as a host and clients can’t see it. I’ve tried as a client and it can’t find servers via search or by typing in IP directly. I’ve tried exact same versions of RetroArch/TyrQuake on 2 x MacOs laptops and same thing, they can’t seem to see each other.

Anyone know what I’m missing?
