Guide is great, except my environment (which can't be renamed) is "My First Elastic BeanStalk Application" - this results in error on CLI "Value 'My First Elastic BeanStalk Application' at 'environmentName' failed to satisfy constraint: Member must have length less than or equal to 23"... stuck
I figured out my own mistakes: [1] the actual name was 'Default-Environment', and [2] I had used the wrong zone when I set up AWS CLI using the 'aws configure' command. Fixed both mistakes and zejoop dot com is back online with a working SSL Cert.
