Hello,
I rent a server on nitrado and it seems to have a problem starting any map, the server gets stuck in lobby.
Did you ever heard about this problem?
Here is the config file 
{ "MaxAccountLevelLock": "0", "MinAccountLevelLock": "0", "AdvertisedLevelCap": "25", "AllowQuickjoin": true, "FixedWarmupDuration": "20", "FriendlyFireEnabled": true, "VSayEnabled": true, "TeamBalanceEnabled": true, "ReadyPercent": "100", "LobbyReadyPercent": "100", "MinPlayers": "1", "MaxPlayers": 16, "CountdownDuration": "20", "GameReviewDuration": "20", "MidGameReviewDuration": "20", "ProgressionSystemEnabled": false, "SpectateWhileDeadProhibited": false, "SpectateOtherTeamProhibited": true, "DemoPrefix": "Dann", "ServerName": "TrueGamers Gameserver", "TimeLimit": "0", "KillLimit": "0", "RoundLimit": "0", "GamePassword": "", "AdminPassword": "marie", "GameDifficulty": "1", "LobbyLockInDuration": "30", "LobbyMapVotingTime": "20", "LobbyMapVotingEnabled": false, "BadgesEnabled": true, "LobbyReadyUpGameStartEnabled": false, "VoteKickEnabled": true, "VoteSurrenderEnabled": false, "VoteSurrenderDelay": "0", "AutoSurrenderEnabled": false, "VotePauseEnabled": true, "VoteRestartMapEnabled": true, "VoteShuffleEnabled": true, "VoteRestartMapTime": 180, "VoteKickPassPercent": "61", "VoteSurrenderPassPercent": "61", "VoteRestartMapPassPercent": "51", "VotePausePassPercent": "51", "VoteShufflePassPercent": "51", "VoteShuffleMinReqTime": "240", "BonusCreditServer": false, "FreeDefenseRespawn": "1", "StopWatchAutoRespawn": true, "FeaturedMap": "", "RotatingMaps": [ { "Map": "Obj_CanaryWharf", "GameMode": "ShooterGame.SGGameInfoObjective" }, { "Map": "Obj_Bridge", "GameMode": "ShooterGame.SGGameInfoObjective" }, { "Map": "Obj_Victoria", "GameMode": "ShooterGame.SGGameInfoObjective" }, { "Map": "Obj_Trainyard", "GameMode": "ShooterGame.SGGameInfoObjective" }, { "Map": "Obj_Whitechapel", "GameMode": "ShooterGame.SGGameInfoObjective" } ] }
