Kubernetes 我无法访问nginx入口和路由53上的kibana

我已经在EKS集群上部署了带有内部负载平衡器和外部DNS的nginx ingress controller，因此我尝试公开kibana，其主机名注册在路由器53上的私有托管区域（my hostname.com）。 但当我使用vpn在浏览器上访问它时，它显示我无法访问该站点。所以我需要知道我做错了什么

以下是所有资源：

我已经检查了我的私有托管区域的记录集，发现kibana.my-hostname.com已经添加，但仍然无法访问它。

Route53将只响应来自您内部和允许的VPC的请求。您无法通过专有网络访问域

要解决此问题，请将您的区域更改为公共区域，或使用带有简单广告的VPN将请求转发到您的专用区域，如前所述

请发布

curl-v kibana.my hostname.com

它向我显示：curl（7）连接失败关于

nslookup kibana.my hostname.com

和

kubectl get pod--show labels

**服务器找不到kibana.my-hostname.com:nxdomain第二个命令正确返回标签，但我已经在使用vpn访问我的vpc内的资源，如上所述，我可以使用VPNB访问在内部负载平衡器上公开的服务，但您是通过ALB的dns名称访问服务，还是通过在您的内部区域上注册的自定义dns访问服务？如果您使用的是Amazon ok提供的dns名称，它可以工作。。。但是，如果是自定义内部路由，53只接受vpc内部资源的请求，如回答中的链接所述。
