I’ll try to figured it out by myself then I can. I had same issues when I change 4.11 to 4.12 without update gamesparks plugin to latest version, but it is normal thing, I think. By the way, when I starts to play around with gamespark -I had looking for incoming/outcoming trafic - it is absolutely zero until I call some requests to server. I suppose you have the latest version of gamesparks plugin installed.P.S. I use blueprint version.
