I have a cpanel reseller account and used Let’s Encrypt to issue SSL certificates for the www, ftp and mail services. Our www service is now hosted by a different server outside of the current providers network and name records at the cpanel reseller account are used to point it that way.
The mail server and our subdomains are hosted on the cpanel reseller account.
The certificate expired two days ago. When I renew I get the following:
There was a problem processing your request
Error issuing certificate
Failed to issue certificate
The Let’s Encrypt HTTP challenge failed: acme error ‘urn:acme:error:unauthorized’: Invalid response from http://catcountry989.com/.well-known/acme-challenge/BXENwZTRiUcnEGvVv48BxlRK8yOcXa1q0Zc9XC5NlXw: " <meta name=“viewport” "
Is there a way to issue the certificate to just the mail.domainname.com service? And what would be the best way to do this?
