Problem was on my side. I sent badly structured json to gamelift and instead of returning me a error, it returned serverip without port.

NVM, error returned. Still no port

I handled that error by extracting port directly from command line arguments instead FURL::UrlConfig.DefaultPort using those instructions: How to get command line parameters in c++? - UE4 AnswerHub
