Failed authorization procedure. cautivo.fibras.com.ar (http-01): urn:ietf:params:acme:error:unknownHost :: The server could not resolve a domain name :: No valid IP addresses found for cautivo.fibras.com.ar
- The following errors were reported by the server:
Detail: No valid IP addresses found for cautivo.fibras.com.ar
To fix these errors, please make sure that your domain name was
entered correctly and the DNS A/AAAA record(s) for that domain
contain(s) the right IP address.
- Your account credentials have been saved in your Certbot
configuration directory at /etc/letsencrypt. You should make a
secure backup of this folder now. This configuration directory will
also contain certificates and private keys obtained by Certbot so
making regular backups of this folder is ideal.
