Hello, I'm trying to install from 0 Arma3 server in Ubuntu 16 , but once started, when I go to the client , kick me , he tells me that the authentication of steam fails. And in the server console , I get the error of S_API FAIL : Not what else to do , I took all day with this. I see people who feel the same, but I can not find the solution. Some clue? Thanks in advance.
