Estou atualmente no processo de configurar um certificado para o meu GitLab-CE, mas estou enfrentando um erro. Gostaria de saber se alguém poderia me fornecer informações sobre a possível causa desse erro e oferecer orientações sobre como resolvê-lo.
Segue erro no Linux - Ubuntu
example@gitlabsinc:~$ sudo certbot certonly --standalone -d gitlabsinc.exemple.net.br
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Requesting a certificate for gitlabsinc.exemple.net.br
Certbot failed to authenticate some domains (authenticator: standalone). The Certificate Authority reported these problems:
Domain: gitlabsinc.exemple.net.br
Type: dns
Detail: DNS problem: NXDOMAIN looking up A for gitlabsinc.exemple.net.br - check that a DNS record exists for this domain; DNS problem: NXDOMAIN looking up AAAA for gitlabsinc.exemple.net.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.
Some challenges have failed.
Ask for help or search for solutions at https://community.letsencrypt.org. See the logfile /var/log/letsencrypt/letsencrypt.log or re-run Certbot with -v for more details.
For the --standalone plugin to work, the hostname is required to have an IP address associated with it in DNS, e.g. an A record for IPv4 and/or an AAAA record for IPv6.
