Access https backend with ingress and traefik - kubernetes

Question

I am trying to use 'Kubernetes Ingress with Traefik, CertManager, LetsEncrypt and HAProxy' for certificates management.
What I want to do is use certificates in my application which deployed on kubernetes.
My application contains following services:
my-app1 NodePort 10.43.204.206 16686:31149/TCP
my-app2 NodePort 10.43.204.208 2746:30972/TCP
So for my-app1 without certificates I was accessing it as http://{IP}:31149/app1. And with certificates I am now accessing it as https://my-dns.com/app1. For this I am using this link. I created following ingress resource:
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: prod-ingress
namespace: my-ns
annotations:
cert-manager.io/cluster-issuer: letsencrypt-prod
kubernetes.io/ingress.class: traefik
traefik.ingress.kubernetes.io/router.tls: "true"
spec:
tls:
- hosts:
- "my-dns.com"
secretName: prod-cert
rules:
- host: "my-dns.com"
http:
paths:
- path: /app1
pathType: Prefix
backend:
service:
name: my-app1
port:
number: 16686
But for my-app2 without certificates I was accessing it as https://{IP}:30972/app2. So as I am already using https for my-app2 but I want to also use certificates for this service.
Any idea how to do this?

Answer 1

So the issue was, I was deploying my application with self signed certificates. So because of this I am getting issue while accessing my dashboard.
So now I just disabled self signed certificates in my application. And now I am able
to access dashboard with domain name https://my-dns.com.
