Hi,
so I had a server with a couple of my friends way back in May 2020. We wanted to revisit it, but upon logging into my account, I couldn't see the server.
The server's IP was yalloverweight.aternos.me, and the account name was yuselid. I have access to the yuselid account but not to the server. I have more proof that it was my server. I don't know what happened to it. I don't remember deleting it or anything.
I can send the support token if that would help. I really hope that the server could be reactivated or something.
Thanks in advance!! 
Btw I think I had the backup featured enabled on my google drive but I don't know how the backup thing works exactly.
