Stop Protection is a safety feature in EC2 that prevents your instance from being stopped by mistake. When it is turned on, you cannot stop the instance unless you first disable stop protection. This is useful for important servers that must always stay running. To stop such an instance, go to the settings, turn off stop protection, and then stop it.

1. When launching the server, you can enable the option to prevent the machine from being accidentally stopped.
2. After launching the server, try to stop the machine.
3. At that time, the system will show a popup indicating that the machine failed to stop. If you want to disable this option, click on the Actions button, go to Instance Settings, and then select Change Stop Protection.
4. After that, uncheck the stop protection option and save the settings.
5. Then, try to stop the machine again, and this time it works — the machine stops successfully.
