What does "before then or you will lose stuff" mean?

I connected to a server and in the bottom left hand corner in green it said that?

Think maybe the server could be closing and if you have a tent there then you need to clean it out "by then or lose stuff".... maybe?

It means someone can't speak the English language but is trying anyway.

A for effort.

The server will be restarted in x minutes. Disconnect before then or you will lose stuff.

If you stay on the server when it goes down then the last minute or so won't save properly so you risk losing anything you picked up or whatever in that time.
