You did something wrong with your server's screens.

 

Screen -S Sever
Then went in the server and started it
Ctrl a d to exit

 

bump

 

Check with htop if there is another PocketMine process running

 

I already said this is the only server running on the dedi

 

Maybe the last one didn't exit properly and you haven't noticed
