Hello guys,
I got a similar problem as him. Today I set up my dedicated server as explained here: https://forums.bistudio.com/topic/139003-tutorial-installation-configuration-of-arma3-dedicated-server/
Everything works fine and the arma3server.exe is starting as it should and looks like this: https://gyazo.com/39dcd117a22b610012006000957bea80.
But I am not able to find the server in the serverlist or connect to it.
This is what the .rpt looks like: http://pastebin.com/ZqKxZEna
Maybe someone can help. Also not sure if i did the Port Forwarding correctly.
