SSL certificate error: The provider encountered an error verifying the DNS settings of your domain name. Please double check your nameserver settings and try again later.
Error detail: Error while resolving DNS TXT records for _acme-challenge.mydomain.io.: NXDOMAIN
Other Information
I have tried multiple times to request the SSL certificate with the same error. I have waited an hour as advised and requested the SSL certificate several times as well. Every time, the ‘Ready’ sign appeared which is very unusual. The provider is Google Trust. Thanks!
How long has it been since you added the CNAME record for the domain validation?
This sounds like a DNS caching issue to me. If you only just added the CNAME record, the client area may already see the CNAME record, but SSL providers may not yet.
This is normal, and just how DNS works, and the solution is just to try later. And by that I mean an hour or two later.
