I am trying to connect to mc.hypixel.net, but it turns out this message. It comes out for some other servers too. I have tried to restart my game or reinstall but it still doesn't work(even reinstall java). Any help? I am running on Mac OS X.
this happens when your minecraft account is logged in by another pc so if you told a friend ur account or a fam menber ask them to get off or you mightve been hacked if you think you were hacked then go to mojang support
