Minecraft Server How To Pause With Noone On

[dense lily]

Hey guys! I've been looking around online and I'm struggling to find anything relating to server sleeping. I'm setting up a server to play with friends, and with my testing i've been doing alone, the server does not seem to stop when nobody is on. I want to find a way to make sure that it will stop (or if i'm just not giving it enough time), because I dont want things to happen when we're gone.

TL:DR = how can I make sure that the game will freeze/stop when everyone is gone
Im running a Neoforge 1.21.1 server with a custom modpack I made, I tried the FreezeHibernate plugin but with my testing it doesn't seem to work

^ All of my research led to settings revolving around other games, nothing to do with minecraft

Also a quick question just to avoid putting in an entirely different thread, if im not paying for the fancy ip, will the normal ip change often?

Heya! The IP will not change, you will keep the same IP the entire time you have the server, unless you have a node move.

Regarding pausing the server when no players are online, in your server properties make sure the section "Pause when Empty Timer" to something like 5 seconds (Refer to ss attached, ignore the -1 as that is what I have for my server lol).
