The certificate of kotronis-plastics.gr is the 1st domain that I mention in my question. My problem is that the statements in the 2nd domain:
pre_hook = apachectl -k stop
post_hook = apachectl -k start
cause problems (see this post).
That’s why I want to edit the entries under [renewalparams]of the 2nd domain (scti.gr) in order to be the same as the 1st. So running only the command:
certbot -d scti.gr -d www.scti.gr -a webroot -i apache -w /var/www/html/scti-site
shouldn’t be enough?
