A common issue many customers experience is when their server seem to automatically just stop multiple times for no reason. In most cases your windows license expired which is the main cause for server stops.
Windows licenses are basically windows trial licenses (windows server evaluation) that are only valid for 180 days. After license expiration you need to either purchase a windows server license by yourself or extend your trial license.
There are many tutorials out there how to extend a windows trial license, here is one of them: https://sid-500.com/2017/08/08/windows-server-2016-evaluation-how-to-extend-the-trial-period/
After extending or purchasing a license, your server wont suddenly stop again.
Note: The expiration time of your current license is placed on the bottom right corner in your server.
