Have you ever tried to investigate a little bit further ?
In the virus total details tab there's the info about that ip. It relates to microsoft azure cloud services. None of the 97 antiviruses detected it as malicious, besides community comments, including the ones about TLauncher (pirated minectaft game launcher) We don't know why it does connect to that ip. It might be an unreal engine data base access for unreal's purposes. We did not make every line of engine code from scratch. We use ready engine that may add side behaviours. And also some plugins. Like game save system. But they are from unreal's marketplace. I sure they does have quality control.

If you will scroll the page down, you'll find screenshots made by the sandbox. For our game there's two screenshots, second shows pop-up dialogue about directX msvc not being installed on the machine, in case with rocket league there's not. May be this is the reason, but we are not sure. We tried to build the game from scratch, and it really does have 100/100 threat score on hybrid-analysis, while AV Detection: Marked as clean. Virus-total have not detected any viruses.
