Fixing the CNAME already exists error

Issue description
When creating a resource, you get this error:
cname:["CNAME cdn.<domain> already exists. Try another CNAME or contact support."]
Solution
The issue occurs because the CDN provider already has a resource with the same host name. Once it is deleted, you can create a resource with that name in Yandex Cloud.
If the issue persists
If the above actions did not help, it may mean that some resources still remain, even if they are inactive. We recommend contacting EdgeCDN support to delete unused resources.
