Why can't I login successfully using Online Services

Development Programming & Scripting

I’ve gone and setup login code to work with the Dev Auth Tool. Yes I setup a connection in the tool and as you can see I’ve used the localhost IP and the token name that I setup in the tool as well. Then on the PlayerController BeginPlay method I call my login method. But no matter what I get the login failure message with the message invalid parameters. The Dev Auth Tool is running when I run my game.

Here’s the Login method found in a GameInstanceSubsystem:

void UMySubsystem::Login()
{
	using namespace UE::Online;

    UE::Online::IOnlineServicesPtr OnlineServices = UE::Online::GetServices();
    UE::Online::IAuthPtr AuthInterface = OnlineServices->GetAuthInterface();

	FAuthLogin::Params LoginParams;

	LoginParams.CredentialsType = LoginCredentialsType::Developer;
	LoginParams.CredentialsId = TEXT("127.0.0.1:8080");
	LoginParams.CredentialsToken.Emplace<FString>("MyTokenName");
   
    AuthInterface->Login(MoveTemp(LoginParams)).OnComplete([](const TOnlineResult<FAuthLogin>& Result)
		{
			if (Result.IsOk())
			{
				UE_LOG(LogOnlineSubsystem, Log, TEXT("Login Successful!"));
			}
			else
			{
				UE_LOG(LogOnlineSubsystem, Error, TEXT("Login Failed: %s"), *Result.GetErrorValue().GetLogString());
			}
		});
}

And then here’s the code in the PlayerController:

void AMyPlayerController::BeginPlay()
{
	Super::BeginPlay();

	UMyGameInstance* GameInstance = Cast<UEOSBlueprintGameInstance>(GetWorld()->GetGameInstance());
	UMySubsystem* OnlineSubsystem = GameInstance->GetSubsystem<UMySubsystem>();
	ULocalPlayer* LocalPlayer = Super::GetLocalPlayer();

	if (LocalPlayer)
	{
		FPlatformUserId LocalPlayerPlatformUserId = LocalPlayer->GetPlatformUserId();
		if (OnlineSubsystem) // null-check subsystem before access
		{
			UE_LOG(LogOnlineSubsystem, Log, TEXT("Logging in PlatformUserId: %d"), LocalPlayerPlatformUserId.GetInternalId());
			OnlineSubsystem->Login(LocalPlayerPlatformUserId);
		}
	}
}

Any help would be greatly appreciated. I want to get this working so I can continue to implement cross play in my game.
