Server browser not working (please help)

Godot Version

v4.3.stable.official [77dcf97d8]

Question

I followed this youtube tutorial on creating a LAN multiplayer browser. It works fine when running two instances on my PC, but doesn’t work when running on separate devices. I am not sure if this is an issue with my code, or a firewall issue. Attached is a zip file of a stripped-down version of the project.

Maybe your local ip range isn’t 192.168.1.___, you could try broadcasting to 255.255.255.255 to reach any local connection.

It is already set to that
