InitSDK timeout using GameLift SDK 5 + UE 5.1

Hello.

I have a project made in Unreal Engine 5.1.1 using the GameLiftSDK 5.0.0 and I'm facing a timeout problem during the call of InitSDK(serverParameters) function.

According to the documentation, the serverParameters values should be set to null when using an EC2 managed in order to get this values directly from the environment. During my local tests, I've observed that this timeout usually happens when some of the server parameter values are not correct.

There's a way to get more detailed logs about what is happening or, at least, check if the server parameter values are being set correctly?

PS. I can't look for the GameSession logs since the fleet activation fails before the creation of any game session.

I'm posting below a code block where I am setting the server parameter values to nullptr:

FServerParameters serverParameters;
serverParameters.m_authToken = nullptr;
serverParameters.m_fleetId = nullptr;
serverParameters.m_hostId = nullptr;
serverParameters.m_processId = nullptr;
serverParameters.m_webSocketUrl = nullptr;
gameLiftSdkModule->InitSDK(serverParameters);
