I have requested a certificate in AWS Certificate Manager for its Domain Name and its Subdomain and it's already issued.
example.com
*.example.com
I have check each domain and subdomain with www and with non-www
https://www.example.com // secured
https://example.com // secured
https://www.subdomain.example.com // not secured
https://subdomain.example.com // secured
I have use S3 bucket for Static Web Hosting and CloudFront for the app.
What is the reason for this? Am I doing this right?
