Hello, my team was just acquired a dedicated server with a Linux OS by Soyoustart (OVH service provider). We had a windows DS before and we haven't any problems, but now some players of my team can't find the server.
We find a temporary solution to counter this problem : we have a TS3 server on the same machine and when the player joins the TS3 server, the Arma3 server appears in the multiplayer menu.
We tried with a web service too but it don't work.
I think the problem is about the Arma 3 client UDP connection with the server (or vice versa).
So, I try a nmap command on udp ports 2302 to 2305 when the arma3server was up and later when it was down : and services responding well.
So I don't know how to resolve this problem. I hope my information can help someone who can find the solutions.
