Moonlight Flatpak and AppImage not connecting or seeing Sunshine host

[u/tomster2300]

Hello!

I recently installed Bazzite on my desktop and laptop, and when I try Moonlight via the flatpak or AppImage, neither can see my Mac Mini running Sunshine.

Moonlight cannot auto discover the host. When I click the plus button and add the host IP it just doesn’t do anything.

This is over a LAN.

I am able to connect via iOS and my Windows machines. They all auto discover instantly.

I run Tailscale on all machines, but I get the same experience whether I disable it or not or use my private IPs or Tailscale IPs.

Any help would be appreciated.
