Dayz commander crashes on custom dayz mode

[Nwoswat 22]

Hi so I have a group of 4 friends (including me) that play dayz regularly we decided to start using commander to get the custom dayz maps, 3 of my friends including me have been using dayz commander for months without any problem but one of my friends cant seem to get it work every time we played he used six launcher not commander.

So he decided he was going to hop over to commander considering its easy to download the custom maps but every time he plays with the commander his game crashes, or when he joins he cant see the names in the lobby and gets kicked even thought everything is up to date. please if anyone knows how to fix this help us because i don't want to ditch him to play custom maps

Is he getting any error messages on screen or are you able to see in game what he is kicked for?

No he doesn't and for us he just disconnects or times out

Is it a steam copy?

Make sure he is not jumping from different maps without closing arma first then fresh loading the new map, this may cause kick issues.

It is a steam copy but im not sure what you mean by jumping from different maps he just starts of a origin server or any dayz server from commander and he gets kicked
