Certbot failed to authenticate some domains (authenticator: apache)

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. crt.sh | 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: www.omp.hashlabs.in

I ran this command: certbot --apache

It produced this output:

Which names would you like to activate HTTPS for?

Certbot failed to authenticate some domains (authenticator: apache). The Certificate Authority reported these problems:
  Domain: www.omp.hashlabs.in
  Type:   dns
  Detail: DNS problem: NXDOMAIN looking up A for www.omp.hashlabs.in - check that a DNS record exists for this domain; DNS problem: NXDOMAIN looking up AAAA for www.omp.hashlabs.in - check that a DNS record exists for this domain

Hint: The Certificate Authority failed to verify the temporary Apache configuration changes made by Certbot. Ensure that the listed domains point to this Apache 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.

Your Apache VirtualHost for that domain and port 80 is wrong. Responses to requests get this error. Port 80 should not be using HTTPS

Hi @tkdhanasekar, and welcome to the LE community forum :slight_smile:

I can't find anything wrong with that DNS entry/zone/provider at this time.
Perhaps it was just transient error.
Please retry with --staging to test DNS resolve now.

We should also have a look at:
sudo apachectl -t -D DUMP_VHOSTS
