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:
andamp13.hopto.org
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)
My web server is (include version):
nginx
The operating system my web server runs on is (include version):
ubuntu server 18.04
My hosting provider, if applicable, is:
self, on an IPS that blocks port 80.
I can login to a root shell on my machine (yes or no, or I don’t know):
Yes
I’m using a control panel to manage my site (no, or provide the name and version of the control panel):
No
