com.amazonaws.services.cloudfront.model.CNAMEAlreadyExistsException

I am trying to add 2 CNAMEs to my CloudFront distribution, but I am getting this error message:

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;

I don't have another CloudFront distrubution, and I don't think anyone else has a distribution with these names since they are very unique:

"www.plataformalatina.com" and "plataformalatina.com"

Can anyone please help?

I just checked a nslookup on the domain you posted, and it's not pointing to a CloudFront distribution? - Gonz
In Route 53 I have two A records for www.plataformalatina.com and plataformalatina.com pointing to my distribution: "ALIAS d206mi07vh816s.cloudfront.net" What else do I need to do? - Luis Lema
The propagation should be 60 seconds, so something in the configuration might be wrong - Gonz
It might be because I'm not able to add the CNAME to my CloudFront distribution. - Luis Lema

I contacted AWS support and turns out someone else had a CloudFront distribution associated with that CNAME.

Did you get confirmation from AWS to know if they're or wild card is not added somewhere else?

You can try this:

  1. Try creating CNAME record instead of alias www.plataformalatina.com CNAME dxxxxxxx.cloudfront.net

Try to add this www.plataformalatina.com to your Distribution.

If this works, remove alias for plataformalatina.com as well and try to add it to CloudFront. CloudFront performs check before it allows you to add any CNAME and in case of Route53 alias record, it sees that it resolves to CloudFront IP address but it doesn't know where is it added.

  1. If above doesn't work:

Follow above article and submit proof to Amazon that this domain belong to you and they're add the CNAME on half of you.
