<p>I have deployed nginx ingress controller with internal load balancer and externalDNS on my EKS cluster so i tried to expose kibana with the hostname registred on route53 with private hosted zone (my-hostname.com).
but when i access it on the browser using vpn  it shows me site can't be reached. So i need to know what i did wrong </p>

<p>here is all the resources :</p>

<p>I have checked recordsets of my private hosted zone and figured that kibana.my-hostname.com has been added but still cannot access it.</p>

<p>Route53 will only respond request coming from your internal and allowed VPC's. You cannot reach the domain out of your VPC.</p>

<p>To solve the issue, change your zone to public, or use a VPN with Simple AD to forward requests to your private zone as described <a href="https://aws.amazon.com/premiumsupport/knowledge-center/private-hosted-zone-directory-service/" rel="nofollow noreferrer">here</a>.</p>
