DayZ Commander - Can't join a working server

[poniat 0]

Hello
I have an problem with my game.
It's about dayz commander, i think.
I wanted to play with my friend on a epoch server, i have installed the newest beta patch for arma, dayz epoch and i still can't play on this server.
I have also played recently on other epoch server and it worked perfectly.
When i try to add this server to favourites, it's showing only the ip adress on the server list,. Dayz commander should show me on the list wchich version of arma and dayz does use this server, but it doesn't show the arma ver., and it's not showing me the number of used slots and real ping (it's 10000 - just not responding?)
When i try to connect this server it's stucks at "wait for the host" message.

The server should work, because my friend connects with no trouble. 

I have also more servers like this on my list, that are not showing the arma version.
Doses anybody know what to do in this situation?
