Error on Dashboard "An error occurred" and unable to create instance due to "Error loading AMI data".

Hello,

When your ec2 instances fail to launch due to issues with our AMI, it could be either:

1. The AMI ID does not exist
   • The AMI might have been deleted after creating the launch template of configuration
   • Solution would be to create a new launch template using a valid AMI
2. AMI might have been created by taking a snapshot of a running instance or any other way and it might not be available yet
   • Solution would be to wait for your AMI to be available before creating a launch template
3. The AMI used to launch the instance doesn't support the selected instance type.
   • Solution would be to check the AMI descriptions in the AWS documentation before selecting the instance type or family, see reference [1].

Please do make sure that the AMI you are trying to use is available in the region where you want to launch your instance and make sure that the service you are using to launch the instance has neccessary access permissions to the AMI.

If none of the above factors are the cause of the problem, then more details of the ami and how you launch the instance will be needed in order to dive deep and find the root of the problem.
