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: instructorcodethenet.net
I ran this command:
It produced this output: sudo certbot --nginx -d codethenet.ddns.net -d www.codethenet.ddns.net -v
My web server is (include version): Linux 24.04.2 LTS
The operating system my web server runs on is (include version):
My hosting provider, if applicable, is:
I can login to a root shell on my machine (yes or no, or I don't know): yes
I'm using a control panel to manage my site (no, or provide the name and version of the control panel): no
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): 2.9.0
Certbot gives an error saying my domain A and AAAA records are nonexistent. I don't want to implement IPv6 as it's not necessary for my setup. The specific error is: "Certbot failed to authenticate some domains (authenticator: nginx). The Certificate Authority reported these problems: Domain: instructorcodethenet.net Type: dns Detail: DNS problem: NXDOMAIN looking up A for instructorcodethenet.net - check that a DNS record exists for this domain; DNS problem: NXDOMAIN looking up AAAA for instructorcodethenet.net - check that a DNS record exists for this domain Domain: www.instructorcodethenet.net Type: dns Detail: DNS problem: NXDOMAIN looking up A for www.instructorcodethenet.net - check that a DNS record exists for this domain; DNS problem: NXDOMAIN looking up AAAA for www.instructorcodethenet.net - check that a DNS record exists for this domain "

Research indicates that I need to have my domain registered, however i'm labbing to see if there's a possibility for me to certify my domain with no expense.
