Connection problem. Possible fix!

[Nuxi]

In the Arma 3 launcher go to Parameters and then to Advanced. Extend Client and Host and put in the port "2302" in both the server ports (Also check mark them if they aren't check markt). That worked for me. But if you have any problems with connecting to other servers just change the ports to "20000" and that should fix it.
