If you are running your EC2 machine in AWS a lot of Cloud functionality is dependent on the AWS EC2 stack named metadata. You can open the browser and check to open the page http://169.254.169.254/latest/dynamic/instance-identity/. If you see your data it means that the machine is properly configured as an EC2 instance, if not it can work but for example, Cloud Watch will not be working. You can try this using this Power Shell script: C:ProgramDataAmazonEC2-WindowsLaunchScriptsInitializeInstance.ps1.
