letsencrypt，nginx，aws和nodejs無法設置

Question

我在AWS EC2實例上使用Nginx設置letencrypt，但是當我執行以下命令時

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

我得到低於輸出

  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.

我不確定我在哪里弄錯了以及如何使它工作。 它向我提出以上問題，然后我做出回應，但是當它獲得證書時就會拋出錯誤。

任何解決方案表示贊賞。

更新

順便說一句，我沒有在上述輸出中注冊任何域名。 出於這個原因，我將它們添加到aws Route 53中。

Answer 1

根據以下錯誤，必須注冊域名，以便DNS可以找到它。

詳細信息：DNS問題：NXDOMAIN在dnestaging2.com上查找A

根據有關使用Amazon Route 53注冊域名的文檔，該域必須在AWS Route 53上注冊或從另一個注冊商轉移。 使用注冊的域名。
