Server Shutting Down

I opened my pixelmon server and was about to log in, and then when i was in the middle of logging into the server it said the connection was terminated and the server just turned of when it had about 40 more seconds until it was shut down automatically and now ive got to wait 70 minutes just to open it back

i dont care about the queue but please fix this and make servers shut down only when the timer ends and not 40 seconds before
