Validation timed out
Domain verification will fail 72 hours after the request if the domain is not assigned to the site.
Remove verification time out of the domain, then re-register and verify it.
Also, check another document for troubleshooting on domain validations.
If the "CNAME is used by other CDN" error occurred when you're attaching the domain name to your site
If you get the following error: " used by other CDN," 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.
Detach that custom domain from another CloudFront Distribution you manage.
Remove an alias and custom certificate from current or disabled CloudFront.
Locate the previously used service associated with that custom domain and remove/delete it.
Disable Webhosting on S3
Your AWS S3 may use it as its bucket name with Website hosting enabled.

The most common cause for this error is trying to set up and visit a custom domain that is not attached to the site. To recap the domain process, you must validate the domain, attach the domain, and update DNS records to point to Shifter.
The solution to this is to attach the domain to the Shifter Dashboard.
To use a custom domain on Shifter, first, you will need to validate that domain. To do this, start by following the steps in our How to guide on assigning a domain.
If you've followed those steps and are still having trouble validating that domain, here are a few tips to check your setup.
Double-check your CNAME record
If you've copied and pasted your validation CNAME from the Shifter Dashboard, it may include a few extra characters or the domain itself.
The record does not need to include the top-level domain.
For example, here we are using the www version of your domain.
Here's another example of using the non-www version of your domain.
Check if your record has propagated.
Depending on your DNS provider or TTL, you may need to wait for the new record to propagate. To check this process, you can use a site like experte.com/dns-check to check the status and validate your record.
The difference between attaching the domain and the value of CNAME on your DNS causes a certification mismatch error.
