Oh sorry didnt know about the general.
I deactivated family share on the main account. When i bought it i still had it on tough.
I will completely reinstall the game and try that, if that doesnt work i will refund it most likely.
But connecting via singleplayer is working fine btw.
Update:
I needed to completely reinstall the whole game like you recommended, it had the family share data still apparently. I could connect on Gen 2.
