I made a server and everything works and i didnt get a single error since i made it. But my brother can only join half the time. It says connectoin failed after it is at a black screen that only says loading right after he clicks on my server in the server list. the rest of the time he logs in perfectly without an error. i dont change any settings or things like that. I used the conans server files and this video to help me (theres two parts) http://www.youtube.com/watch?v=ONFYu_ngsz8&feature=youtu.be if you could help me thanks : )

heres the next part of the video http://www.youtube.com/watch?v=mKUD8I70bRY&list=FLsVK5AeidlY9LSVokKgq5Ow&index=5&feature=plpp_video

I dont know how to do it that way but I have a private server i made which ha all the items vechicle and zombie spawns the proplem is that for some reason my brother can only join half the time but the rest it just says connection failed so if you can fix that then I can get.u a working server
