Dedicated Server Not Showing up on Server List

So, recently I brought up a dedicated server for a few friends and I to enjoy and build on… the issue I’m running into is that no matter what I try I can’t seem to get the server to appear on the list.

Any tips would be welcomed, because I’m out of ideas.

Same Problem here, the Friends wo use direct connect are able to connect and play on the server just fine but its not appearing on the list.

How does the Server announcement Process even work? Or is there another setting to be made in the configs to for example put in the public ip adress of the server?
