Network Discovery is not working over multiple devices.

Okay so I have spent the past 48 hours trying to figure this out but I can’t. I’m trying to use the Unity Network Discovery component to have the clients find any local servers.

All I want is for a player to be able to host a server and other players, that are on the same wi-fi, will see this server and be able to join without the need for previously knowing the host’s IP address.

I’ve been able to do this with network discovery when the applications are on the same computer but when trying to connect to other computers the network discovery does not pick anything up.

I’ve also tried using Network Transport but that doesn’t seem to work either.

I briefly looked over UNET but from what I have seen it seems that I would have to pay for their services which is not ideal as these games are LAN games and not online games.

If anyone could help me that would be absolutely amazing!

Wireshark also helped me a lot to detect a Windows 10 firewall problem. The issue is that broadcasts do work but Unity only receives them when you switch off your firewall. Maybe you can also change some firewall settings instead to be on the safe side. Which devices operating systems were you using?
