i’m actually working on an intranet dokuwiki that shall not be access from the internet.
Its running on Apache2 on a Debian 9 Stretch and python-certbot-apache to create the cert.
By trying to get a cert I get the Report DNS problem: NXDOMAIN looking up A for wiki.domain.de
I have read now, that it is still possible to get a cert for this server with something called http-01 challange, but I do not get the way how to bring it up.
If someone got through this and can explain or provide me with a link to a guide to get this running I would be very happy.
