My issue is that I do not see letsencrypt try to access my server on the firewall.
If I try to access the acme-challenge file externally (from my phone) I do have access to the file.
Thus the server is properly setup and the ddns is properly resolving the host fqdn
What could be the issue?
My domain is: study.klomp.ca
I ran this command: sudo certbot certonly --apache --dry-run -d study.klomp.ca
It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator apache, Installer apache
