I never been on this server.. Someone else is having the same ip as me lol ._. And i have bought minecraft..
Hey @Rebelianka try restarting you're router or see if you have any active vpn. Kind Regards, xReveal.
I think if that's your first time to register to the server , check if any of your family members made 3 accounts before or something , or if you made 3 already then rip idk what to do..
