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.
I am a newbie on web dev, but i think there is no issue with A record of my domain name.
My domain is: tdmworld.net
I ran this command:sudo certbot certonly --agree-tos --email gopinath_mandala@epam.com --webroot -w /var/lib/letsencrypt/ -d tdmworld.net -d www.tdmworld.net
It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator webroot, Installer None
