Issues adding a custom domain to my Amplify application

Question

Hello, as the title suggests i've been having difficulties connecting my route53 registered, hosted zone domain to my Amplify application via the Custom Domains approach.

The error i am currently seeing is:
SSL setup failed
One or more of the CNAMEs you provided are already associated with a different resource. (SDK Attempt Count: 1)

I have removed the "previous" application's records from the hosted zone, deleted the custom domain in the app, and attempted to re-add the custom domain in several ways. I've attempted to use Q to identify the issue but haven't had any success either.

Your help is appreciated!

You may identify the conflict by checking other Amplify Apps, CloudFront Distributions, ACM Certificates and Roue53 Records, you may then try t clean up DNS records in Route 53 to see whether this can help.

Hey,

Hope you're keeping well.

That error usually means the CNAME validation records for the ACM certificate are still tied to another CloudFront distribution or Amplify app. In Route 53, check the hosted zone for any `_acm-validation` CNAME records and delete or update them so they match the new certificate Amplify is provisioning. Also verify in the ACM console (same region as Amplify) that no other certificate is using the same domain name, and remove old certificates if they’re no longer needed. Once the DNS is cleared, retry adding the custom domain in Amplify so it can create fresh validation records.

Thanks and regards,
