Let's Encrypt SSL certificate for subdomains
Is it possible to warn me beforehand if I try to request a Let's Encrypt SSL certificate for subdomains including auto-subdomain www where there is no correct DNS A-record present?
The server could not connect to the client to verify the domain :: DNS problem: NXDOMAIN looking up A for www.subdomain.domain.tld. Skipping
Letsencrypt checks the subdomain but of course if there is not *.subdomain record I get the above warning. I can do this manually but this is something easily forgotten. Maybe ISPConfig could even create the necessary record automatically, CNAME record *.subdomain pointing to the subdomain itself?
