You control your server at the top of the server page:
- Start boots the server. On first start it often still downloads game files, which can take a few minutes.
- Stop shuts it down cleanly: the world is saved, then it exits.
- Restart is Stop and Start in one – needed e.g. after changing startup variables or adding new mods.
- Kill switches the server off immediately without saving. Only use it if the server hangs while stopping – unsaved data may be lost.
You can see whether the server is running in the “Live from the server” display with CPU, memory and storage.
Set up regular restarts – with a warning for players – using schedules.
