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.
