Hi, sorry for resurfacing this old thread, but I have been trying to get Lyra Multiplayer to work aswell. I have configured EOS on the dev portal and put all the stuff in the .ini, I am building from source and I get a steam overlay and the “You are connected” Message, however at the bottom of the screen it still says “Not Logged In” and when I attempt to start a game I get this error:
