I'm running a Dayz mod game server with the latest 1.8.6.1 version, and there is one player who is not able to connect, there are tons of other players who are able to connect and play normally but 1 can't. He is downloading mission file, after it's finished he can see dayz server logo with the empty progress bar they he is going back to lobby with the download progress bar stuck at 100%. I suggested him reinstalling both arma and dayz mod and then check the steam file integrity and he did, that didn't help. There is nothing worrying in his .rpt log, all I can see in the server .rpt is: 2015/10/28, 22:41:52 NetServer::SendMsg: cannot find channel #2049037743, users.card=42015/10/28, 22:41:52 NetServer: users.get failed when sending to 20490377432015/10/28, 22:41:52 Message not sent - error 0, message ID = ffffffff, to 2049037743 (PLAYER_NAME)2015/10/28, 22:41:52 NetServer::SendMsg: cannot find channel #2049037743, users.card=42015/10/28, 22:41:52 NetServer: users.get failed when sending to 20490377432015/10/28, 22:41:52 Message not sent - error 0, message ID = ffffffff, to 2049037743 (PLAYER_NAME) and something from earlier this afternoon 2015/10/28, 15:13:36 NetServer: users.get failed when sending to 8754626672015/10/28, 15:13:36 Message not sent - error 0, message ID = ffffffff, to 875462667 (PLAYER_NAME)2015/10/28, 15:13:36 NetServer::SendMsg: cannot find channel #875462667, users.card=02015/10/28, 15:13:36 NetServer: users.get failed when sending to 8754626672015/10/28, 15:13:36 Message not sent - error 0, message ID = ffffffff, to 875462667 (PLAYER_NAME)2015/10/28, 15:13:36 "infiSTAR.de PlayerDisconnected: _uid: 76561198050555137 _name: PLAYER_NAME"2015/10/28, 15:13:36 "get: STRING (XXXXXXXXXXXXXXX), sent: STRING (76561198050555137)"2015/10/28, 15:13:36 "Player UID#XXXXXXXXXXXXXXX CID#?

Also I cannot find this user in the database. //Problem was solved by removing class sockets from basic.cfg
