I associated an SSL certificate with my Amazon CloudFront distribution, but I can't access my domain name over HTTPS. Why?
To resolve problems with accessing your domain name over HTTPS, check the following:
- Your SSL certificate's domain name must be added as an alternate domain name (CNAME) in your CloudFront distribution's settings. For more information, see Adding and Moving Alternate Domain Names (CNAMEs).
- The domain name of the SSL certificate must be consistent with the domain name associated with the CloudFront distribution. For example, if you issue an SSL certificate for *.example.com, then the CloudFront distribution will support domain names such as abc.example.com or 123.example.com. However, an SSL certificate for *.example.com won't support domain names such as abc.123.example.com. To use abc.123.example.com as a domain name, you need an SSL certificate for either *.123.example.com or abc.123.example.com.
- If you're getting cipher or TLS version mismatch errors, verify that your client is using supported SSL or TLS protocols and ciphers for communication between viewers and CloudFront.
- Verify that the status of your CloudFront distribution is Deployed. If the status is still InProgress, you might not be able to access the domain name because data is still propagating across edge locations.
- If you recently updated your SSL certificate on AWS Certificate Manager, verify that the certificate renewal status is Success. It might take several hours for the certificate renewal process to complete. For more information, see I renewed my Amazon-issued SSL certificate or reimported my certificate to ACM. Why does CloudFront still show the old certificate?
- If you're using an Amazon Simple Storage Service (Amazon S3) bucket for the website that you want to serve over HTTPS, be sure that the bucket name doesn't include periods ("."). For more information, see Rules for Bucket Naming.
