Help Error Domain

[welington.lima]

Good Morning!

Dear ones could help me.

In the configuration we use the command
#certbotcertonly --standalone -D DOMINIO.COM.BR

At the end of the process it is generating an error, could you explain to me what could be causing this error?

Certbot failed to authenticate some domains (authenticator: standalone). The Certificate Authority reported these problems:
Domain: fwgrancursosmatriz.com.br
Type: dns
Detail: DNS problem: NXDOMAIN looking up A for fwgrancursosmatriz.com.br - check that a DNS record exists for this domain

Hint: The Certificate Authority failed to download the challenge files from the temporary standalone webserver started by Certbot on port 80. Ensure that the listed domains point to this machine and that it can accept inbound connections from the internet.

check that a DNS record exists for this domain

Welcome to the community @welington.lima

Just like the message says, you do not have DNS setup for that domain name

Make sure this is a public domain name and setup the DNS for it. Contact your domain name registrar for advice

Perfect!

In this case I need to make this domain public is that it?

It's still just local on our device.

[MikeMcQ]

Yes that is it
