letsencrypt，nginx，aws和nodejs无法设置

Question

我在AWS EC2实例上使用Nginx设置letencrypt，但是当我执行以下命令时

sudo certbot --nginx -d dnestaging2.com -d www.dnestaging2.com

我得到低于输出

  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.

我不确定我在哪里弄错了以及如何使它工作。 它向我提出以上问题，然后我做出回应，但是当它获得证书时就会抛出错误。

任何解决方案表示赞赏。

更新

顺便说一句，我没有在上述输出中注册任何域名。 出于这个原因，我将它们添加到aws Route 53中。

Answer 1

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在dnestaging2.com上查找A

根据有关使用Amazon Route 53注册域名的文档，该域必须在AWS Route 53上注册或从另一个注册商转移。 使用注册的域名。
