Some challenges have failed

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: realsoftware.pro

I ran this command:
sudo certbot --apache -d test.realsoftware.com

It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Requesting a certificate for test.realsoftware.com

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

Welcome @zubair999

The --apache option uses an HTTP Challenge. This challenge requires an A and/or AAAA address in the public DNS to name the public IP. The Let's Encrypt servers uses that public IP to send the challenge.

You don't have the required record(s) in your DNS for the test subdomain. You do for your registered domain but not the test subdomain.
