Basically, if I'm connected to a minecraft server on computer A, then can I connect to the same server on computer B without server noiticing disconnecting on computer A and reconnecting on computer B? Back in 2020 I think there was an exploit, witch allowed to get anyones session id and join the server that they were playing on, and the game was kicking the legit player, and letting the hacker join, but now when I try to connect to a server that I'm connected to on computer A on computer B, then I get such message:
EDIT: I'm trying to join 2b2t.org on minecraft version 1.12.2 using impact cheats.
