DNS Validated Let's Encrypt Certificates

[superflip1]

Problem

When trying to obtain certificates for a FQDN like system.test.co.at (you normally own test.co.at and not co.at), the script fails.
The reason is, that in bash script "certbot-hetzner-auth.sh", only the last two parts of the name are striped - resulting in "co.at".

search_name=$( echo $CERTBOT_DOMAIN | rev | cut -d'.' -f 1,2 | rev)

Suggested Fix

A quickfix, if you are only using cers in such domain structure like test.co.at ist to change script to:
search_name=$( echo $CERTBOT_DOMAIN | rev | cut -d'.' -f 1,2,3 | rev)

Maybe it is better to cut only the hostname, but I'm not sure, if this would result in any other issue.
