Is there a way to prevent this error from happening in the future by optimizing server settings?

While you can't guarantee it will never happen, optimizing server settings helps. Regularly check and update mods and plugins, monitor server performance and upgrade hardware as needed, use a robust and stable internet connection, and configure the server firewall correctly. Regularly back up server data to minimize data loss if corruption occurs. Consider using a server monitoring tool to proactively identify potential issues before they lead to errors.
