I disconnected for no reason I got this message, I think the server hates me!

I am getting the same second message

Thats what happened to my other acc…….

That probably means that someone who actually owns Minecraft with the same username as you joined the server. And then the username will then be reserved for them.

But the server did bug out a few time and did the same to me

That Happens whenever u join with a username such as CLOWNPIERCE but the og name was ClownPierce u willl get the message about  the nlogin because the game will not let u join with a username wich has different caps.

That's why I made my real Minecraft acc my eaglercraft acc.
