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: ncop.tech
I ran this command: certbot certonly --nginx -d ncop.tech
It produced this output:Certbot failed to authenticate some domains (authenticator: nginx). The Certificate Authority reported these problems:
Detail: DNS problem: SERVFAIL looking up A for ncop.tech - the domain's nameservers may be malfunctioning; DNS problem: SERVFAIL looking up AAAA for ncop.tech - the domain's nameservers may be malfunctioning
Hint: The Certificate Authority failed to verify the temporary nginx configuration changes made by Certbot. Ensure the listed domains point to this nginx server and that it is accessible from the internet.
