I’ve previously had a certificate that I validated on port 443 before that approach was removed. Since it was just renewing since then, it was fine until I did a new install to upgrade to 18.04. I didn’t properly backup letsencrypt so I have been trying to re-certify. I have no-ip for the domain dns, and can add TXT DNS entries but that doesn’t seem to be an option anymore. Any suggestions?
My domain is:
I ran this command:
sudo ./certbot-auto certonly --standalone --preferred-challenges tls-sni -d andamp13.hopto.org
sudo certbot certonly --standalone --preferred-challenges dns -d andamp13.hopto.org
and other variations
It produced this output:
either: timed out trying to connect for port 80 solutions, or no valid verification for this host. (paraphrasing)
