Not able to generate ssl certificates

Help
1

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:

stg-cita.com

I ran this command:

sudo certbot certonly --agree-tos --email amit@wiz.asia --webroot -w /var/lib/letsencrypt/ -d stg-cita.com -d www.stg-cita.com

It produced this output:

I see you've corrected your opening post in your previous thread where I also commented already. Let's continu there. I'll close this thread in favor of the first one.
