Can somebody guide me thought that? Because for the HTTP challenge I get following error:
`Certbot failed to authenticate some domains (authenticator: nginx). The Certificate Authority reported these problems:
Domain: jonode.duckdns.org
Type: dns
Detail: no valid A records found for jonode.duckdns.org; no valid AAAA records found for jonode.duckdns.org
Domain: jopanel.duckdns.org
Type: dns
Detail: no valid A records found for jopanel.duckdns.org; no valid AAAA records found for jopanel.duckdns.org
Hint: The Certificate Authority failed to verify the temporary nginx configuration changes made by Certbot. Ensure the listed domains point to this nginx server and that it is accessible from the internet.
Some challenges have failed.
Ask for help or search for solutions at https://community.letsencrypt.org. See the logfile /var/log/letsencrypt/letsencrypt.log or re-run Certbot with -v for more details.
`
and for the dns challenge he wants me to deploy a TXT DNS record and I have no idea how to do that
