"LogOnline: OSS: Unable to create OnlineSubsystem module Steam"

Hello, I’ve got this log when I inserted the default engine ini stuff for the steam subsystem:

LogPluginManager: Mounting plugin AdvancedSteamSessions
LogPluginManager: Mounting plugin OnlineSubsystemSteam
LogPluginManager: Mounting plugin SteamShared
LogSteamShared: Display: Loading Steam SDK 1.47
LogSteamShared: Steam SDK Loaded!
LogOnline: OSS: Creating online subsystem instance for: Steam
LogOnline: Display: STEAM: OnlineSubsystemSteam::Shutdown()
LogOnline: OSS: Unable to create OnlineSubsystem module Steam

This is what i’ve put in my ini

[/Script/Engine.GameEngine]
+NetDriverDefinitions=(DefName="GameNetDriver",DriverClassName="OnlineSubsystemSteam.SteamNetDriver",DriverClassNameFallback="OnlineSubsystemUtils.IpNetDriver")

[OnlineSubsystem]
DefaultPlatformService=Steam

[OnlineSubsystemSteam]
bEnabled=true
SteamDevAppId=480

[/Script/OnlineSubsystemSteam.SteamNetDriver]
NetConnectionClassName="OnlineSubsystemSteam.SteamNetConnection"

Does anybody know what does this mean?
