This error can be caused by any of the following:
1. Typographical error
What to do: Check for any wrong spellings, extra characters, etc.
Important:
Some providers require you to input the complete name (subdomain and domain)
videos.mywebsite.com |
|
Others have the domain pre-filled and you only need to provide the subdomain.
videos | mywebsite.com |
2. An unsafe domain
A domain may be tagged as unsafe if it contains deceptive content, including malicious ads
3. Additional information required by AWS
Usually, the first 2 DNS records are enough for most providers.
Some providers, however, require an additional DNS record to be created. In this case, you have to complete all three records.
