Run Steam Update when Astroneer receives a patch or when the game reports a client/server version mismatch.
- Open your Astroneer server in the control panel.
- Create a backup, then stop the server.
- Click Steam Update.

- Wait for the update task to finish before starting or changing the server.
- Start the server and reconnect with an updated Astroneer client.
If the service does not return to a running state, check Log Viewer for the first startup error before running the update again.
