Server not showing in Server Browser

Hey guys,

Anyone know what I have to do or how to get a server showing up in public Server Browser? It’s a server hosted with Multiplay and is set to Public in their settings.

The only way someone can join right now is if they know the actual I.P to the specific server.

It’s running about 6-7 hours now with about 10 people on it. Would really help if I could get it to show up in server browser so others can find it too…
