Hi, thanks for the reply !
Well, unfortunately after this line Caddy seems to keep trying to get the certificate, but to no avail.

Please forgive me if this is a dumb question, but is there anything else I should have configured apart from the setup indicated in my first post ? I have followed the steps explained in this post How to use DNS provider modules in Caddy 2, but I am still a bit lost as to whether or not I need to apply the steps specified in GitHub - caddy-dns/acmedns as well, especially adding a CNAME record in my DNS records ; do I also need to follow these ? Sorry to bother you !
