Turning off the server

Привет. Я не могу понять, почему сервер был выключен. Вот ссылка на журнал. Он работает хорошо, и вы можете играть в него некоторое время, но затем он выключается. Помогите пожалуйста

The problem is that the server shuts down after about 20 minutes of the game. There were no problems with the connection yet. I don't know how else to describe it. I fly around the world in creative mode and load a small section of the map, then the server saves and shuts down. There is no such problem in a single player game.

did I not dropped the reference to the journal or this is not what you need?
