Solved Server not stopping, why?

Well recently I got some problem. When I used screen ./start.sh it started the server but when I closed PuTTy, and re-oppened it I wanted to close the server I did killall screen but my server was still on, when I did ./start.sh I got that a server is already running on that port. The server was open tho but whenever I tried to join I got stuck in syncing pack with server. And I know this stuck problem is because of opening server through screen. Anyway to close a server after opening it through screen? Thanks for reading.

 

Are you using Linux to host your server?

 

Yes I'm using Linux, Ubuntu.

 

How do you stop your server? You kill it (directly closed the window) or you do "stop"?
If you use the first method, then you should never do it again

 

I actually closed directly after screen ./start.sh, the server remains open but can't be closed.

 

Do you find a process with the command php?

 

I don't think so

 

Fixed, thank you all.
