IMPORTANT NOTES:
- The following errors were reported by the server:
Domain: dnestaging2.com
Type: connection
Detail: DNS problem: NXDOMAIN looking up A for dnestaging2.com
Domain: www.dnestaging2.com
Type: connection
Detail: DNS problem: NXDOMAIN looking up A for www.dnestaging2.com
To fix these errors, please make sure that your domain name was
entered correctly and the DNS A/AAAA record(s) for that domain
contain(s) the right IP address. Additionally, please check that
your computer has a publicly routable IP address and that no
firewalls are preventing the server from communicating with the
client. If you're using the webroot plugin, you should also verify
that you are serving files from the webroot path you provided.
- Your account credentials have been saved in your Certbot
configuration directory at /etc/letsencrypt. You should make a
secure backup of this folder now. This configuration directory will
also contain certificates and private keys obtained by Certbot so
making regular backups of this folder is ideal.
我不确定我在哪里制造错误以及如何使这项工作。它问我上面的问题，我回答他们，但是当它获得证书时，它会抛出错误。
任何解决方案赞赏
UPDATE
顺便说一句，我没有在上面的输出中注册任何域名。我将它们添加到53号公路，因为我正在使用它们。
根据以下错误，必须注册域名，以便DNS可以找到它。
详细信息：DNS问题：NXDOMAIN查找A for dnestaging2.com
根据Registering Domain Names Using Amazon Route 53上的文档，域名必须在AWS Route 53上注册或从其他注册商转移。使用注册的域名。
