Nginx Proxy Manager not secured in Cluster

[dniald]

Hi everyone,

I'm currently deploying an application on Amazon EKS and using Nginx Proxy Manager to manage my proxy configurations. However, I've encountered an issue where my application is not showing as secured (no HTTPS).

Here's my setup:

Amazon EKS cluster

Nginx Proxy Manager for handling proxy configuration

I've followed the standard setup procedures, but my application still doesn't show as secured when accessed via the browser.

Can anyone provide guidance on what might be causing this issue or what additional steps I might need to take to ensure my application is secured properly?

Do i need to use custom SSL? If that so, which path need to insert custom SSL?
Or what did i miss?

Thanks in advance for your help!

Below are my manifest:
