Heres how to config the netdrivers on 5.6+

Update server DLL files

The fix above is correct but its missing one line which tells the engine a client has connected.

SteamSubsystem->TriggerOnSteamServerLoginCompletedDelegates(true);

void FOnlineAsyncTaskManagerSteam::OnSteamServersConnectedGS(SteamServersConnected_t* CallbackData)
{
    FOnlineSessionSteamPtr SessionInt = StaticCastSharedPtr<FOnlineSessionSteam>(SteamSubsystem->GetSessionInterface());
    if (SessionInt.IsValid())
    {
        SessionInt->bSteamworksGameServerConnected = true;
        SessionInt->GameServerSteamId = FUniqueNetIdSteam::Create(SteamGameServer()->GetSteamID());
        SteamSubsystem->TriggerOnSteamServerLoginCompletedDelegates(true);
    }
}

STEAM NET DRIVER < BROKEN EVEN AFTER THE ABOVE FIX

[SocketSubsystemSteamIP]
bAllowP2PPacketRelay=True
P2PConnectionTimeout=300
P2PCleanupTimeout = 100

[/Script/Engine.Engine]
!NetDriverDefinitions=ClearArray
+NetDriverDefinitions=(DefName=“GameNetDriver”,DriverClassName=“SocketSubsystemSteamIP.SteamNetDriver”,DriverClassNameFallback=“/Script/SocketSubsystemSteamIP.SteamNetDriver”)

[/Script/OnlineSubsystemSteam.SteamNetDriver]
NetConnectionClassName=“/Script/SocketSubsystemSteamIP.SteamNetConnection”

STEAM SOCKET NET DRIVER < WORKING WITH ABOVE FIX

[SocketSubsystemSteamIP]
bAllowP2PPacketRelay=True
P2PConnectionTimeout=300
P2PCleanupTimeout = 100

[/Script/Engine.Engine]
!NetDriverDefinitions=ClearArray
+NetDriverDefinitions=(DefName=“GameNetDriver”,DriverClassName=“/Script/SteamSockets.SteamSocketsNetDriver”,DriverClassNameFallback=“/Script/SteamSockets.SteamNetSocketsNetDriver”)

[/Script/OnlineSubsystemSteam.SteamNetDriver]
