英文:
AWS - DNS fails to Elastic IP
问题
我一直在网上搜索并严格按照指南操作，但在成功进行DNS解析方面遇到了问题，希望你能帮忙。
我有一个托管基本Web应用程序的EC2实例，并附加了弹性IP地址。导航到弹性IP成功，我可以访问该应用程序（浏览到 http://xx.xxx.xx.xxx）。
我已经通过Route 53注册了一个域名，它正在显示。我已经创建了一个托管区域 - 最初，域名服务器与域名注册不匹配，并且测试记录失败了。我已经更改了NS详细信息以与注册的域名匹配，现在测试记录成功了。
我已经在托管区域中添加了一条记录（记录类型A，我已经验证该值是弹性IP，TTL 300在简单路由上）。这导致在尝试导航到该地址时出现 ERR_NAME_NOT_RESOLVED 错误。
我想不出还要提供什么其他信息。令人恼火的是，我之前按照相同的步骤操作，第一次就成功了，但我为了进行深入调试而将实例拆除了！

我有一个公共子网，NACL如下：

出站：
100 All traffic All All 0.0.0.0/0 Allow* All traffic All All 0.0.0.0/0 Deny
谢谢！

I've been scouring online and following guidance to the letter but hitting an issue getting a successful DNS resolution, I hope you can help.
I have an EC2 instance hosting a basic web app, with an Elastic IP attached to that instance. Navigating to the Elastic IP is successful and I can access the app (browsing to http://xx.xxx.xx.xxx).
I've registered a domain through Route 53 and that is displaying. I've created a hosted zone - initially the Name Servers didn't match the domain registration and a Test Record failed. I've changed the NS details to match that of the Registered Domain and the Test Record now succeeds.
I've added a record to the Hosted Zone (Record type A, I've verified the value is the Elastic IP, TTL 300 on Simple Routing). This results in a ERR_NAME_NOT_RESOLVED error when trying to navigate to the address.
I can't think of what other information to provide. Annoyingly I followed the same steps previously and it worked first time but I tore the instance down for intense debugging!

I have one public subnet for which the NACLs are:

Thanks!

我已解决此问题。对于其他遇到相同问题的人 - 请在您注册的域中更正域名服务器，而不是在托管区域中。

I've resolved this. For anyone else having the same issue - correct the Name Servers in your Registered Domain, rather than in your Hosted Zone.
