Unable to apply for Certificate: the domain's nameservers may be malfunctioning

[Goojoe]

My domain is:

goojoe.top

I ran this command:

acme.sh --issue --dns dns_cf -d goojoe.top -d *.goojoe.top

It produced this output:

DNS problem: SERVFAIL looking up TXT for _acme-challenge.goojoe.top - the domain's nameservers may be malfunctioning

My web server is (include version):

 nginx/1.22.1

The operating system my web server runs on is (include version):

Debian 11

My hosting provider, if applicable, is:

my.frantech.ca

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):

acme.sh v3.0.5

Just like it says, your DNS servers are misconfigured and aren't returning valid results. Check your DNSSEC configuration. You need the public to be able to resolve your domain name before you can get a certificate for it.

Thank you. I forgot to set DNSSEC when I changed the DNS service provider before. Now I have succeeded
