Hello, I just created my server in MTA SA, and so that it can appear to my friends, I use Radmin VPN with my friends that we are going to play, when we enter the server we are in free mode for a few minutes, before I have already configured the acl so that my friends register on the server, but after a few minutes, it automatically expels my friends, up on the server it says that my friend has been expelled, saying Time expired, what can I do so that he does not expel them?
