If "CNAME is used by other CDN"error occurred when you're attaching domain name to your site

If you get the following error: " used by other CDN", it means you cannot assign that domain to your account because it's currently used by another Amazon Web Services (AWS) account.

This could also include other products which are built on top of AWS.

Possible Solutions

  • Detach that custom domain from another CloudFront Distribution you manage
  • Locate the previous used service associated with that custom domain and remove/delete it
  • Disable Webhosting on S3
    Your AWS S3 may use it as a its bucket name with Website hosting enabled.
