CloudFront - One or more of the CNAMEs you provided are already associated with a different resource
Hi,
I have a situation where there is a CloudFront distribution in one AWS account and Route53 in another AWS account (not related in AWS), then I do the following:
- I switch CNAME in Route53 to use CloudFront distribution - everything works on HTTP (both through CloudFront domain name and through the Route53 domain name)
- I configure CloudFront to use SSL Certificate - everything works while saving (but there is error on HTTPS - 503)
- I update 'Alternate Domain Names (CNAMEs) on CloudFront - I get an error while trying to Save
com.amazonaws.services.cloudfront.model.CNAMEAlreadyExistsException: One or more of the CNAMEs you provided are already associated with a different resource. (Service: AmazonCloudFront; Status Code: 409; Error Code: CNAMEAlreadyExists;
Which would suggest that CloudFront sees a CloudFront distribution (itself) already configured in the CNAME and fails.
Any suggestions how to go around this are appreciated!

It sounds like there is another distribution created with the same (or an overlapping) CNAME configured - this could be the same or in any AWS account.
You should check your CloudFront resources, as well as any other services that may create a cloudfront distribution on your behalf (such as API Gateway).
Failing that, reach out to support with more specific information and they'll be able to provide more specific guidance.
For me, it was an old AWS Amplify app that I had created while following a tutorial on YouTube. If anyone else has this issue you may need to delete an app you suspect has the same CNAME.
I have deleted all my cloudfront distributions still I am facing same issue why ? I want to delete a certificate also . It is showing used in cloudfront resources . but I have no distribution
