CloudFront and ALB Integration

Question

CloudFront - ALB - EC2(Wordpress)
                     - S3 (OAI)

I'm trying to configure something like the above. But there are some problems.
[ACM: example.com, *.example.com]
HTTPS communication using CloudFront's CNAME and ACM(N.Virginia) + ALB's ACM(Asia/Seoul).
With this configuration, a 502 error occurs when connecting to the xxxx.cloudfront.net domain of CloudFront.
Conversely, if I register the example.com - xxxx.cloudfront.net A record in Route53 and access the A record, the page loads normally.

Please tell me the answer to the problem.

Answer

Hello,

When you setup HTTPS origin in CloudFront, the certificate returned from the origin must be valid and include one of the following domain names:
- The domain name in the origin’s Origin domain field (the DomainName field in the CloudFront API).
- The domain name in the Host header, if the cache behavior is configured to forward the Host header to the origin.

Please refer to this document for further information: https://go.aws/3Q0VBuR
