Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is:
I ran this command:
sudo certbot --nginx
It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Requesting a certificate for krill.egihosting.com
Certbot failed to authenticate some domains (authenticator: nginx). The Certificate Authority reported these problems:
Detail: no valid A records found for krill.egihosting.com; no valid AAAA records found for krill.egihosting.com
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.
