I had a dedicated server in one Pc with shared internet conection to my LAN. Until host version X4 I was able to conect to my server via internet, but now, with x10 version my server doesn't appear in the list of game online servers.
The dedicated server is online by itself, but I can't see it.

Press the second button on the multiplayer menu, choose local, enter the IP (127.0.0.1 if you run the dedi from the same coumputer)

Ok. Now I can join in especific server by entering its name, though I do not see its name in the list.

It's irrelevant you not seeing it in the in-game list.

Probably cos you are not showing empty servers, had the same problem myself, when updating your serverlist there are 4 options at the bottom, Privat, Public, Empty and Can Reset, if no one is on your server, it will be empty, and not default shown in server list...
