Steam API disabled. Unable to create OnlineSubsystem module Steam.

I’ve looked at countless other questions about this but can’t find a solution. To my knowledge, I have done everything I was supposed to do via:

In fact, that page seems outdated because when I went to install Steamworks in the 4.8 retail engine binaries, it was already there, in folder Steamv132, complete with all the required Steam DLLs. It also appears that rather than adding code into MyGame.Build.cs, all that is required is uncommenting a few lines there. Anyway, here is what I have done:

I have added this code to:

##DefaultEngine.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"

##MyGame.Build.cs

// Uncomment if you are using online features
PrivateDependencyModuleNames.Add("OnlineSubsystem");
if ((Target.Platform == UnrealTargetPlatform.Win32) || (Target.Platform == UnrealTargetPlatform.Win64))
{
    if (UEBuildConfiguration.bCompileSteamOSS == true)
    {
        DynamicallyLoadedModuleNames.Add("OnlineSubsystemSteam");
    }
}

##MyGame.Target.cs
public MyGameTarget(TargetInfo Target)
{
Type = TargetType.Game;
bUsesSteam = true;
}

I get the following warnings:

 LogOnline:Display: STEAM: Loading Steam SDK 1.32
 LogOnline:Warning: STEAM: Steam API disabled!
 LogOnline:Display: STEAM: OnlineSubsystemSteam::Shutdown()
 LogOnline:Warning: Unable to create OnlineSubsystem module Steam
 LogOnline:Warning: Unable to load default OnlineSubsystem module Steam, using NULL interface

While the Steam Overlay seems to work fine despite the above warnings, I cannot test multiplayer.

Did you find a solution for this yet?

There was nothing wrong with my setup. You just can’t test multiplayer through Steam on one account for some reason. I had to package the game and send it to a friend in order to test over Steam. Make sure you both have Steam open before running the game.

For help on packaging:
