how to setup multiple node balancers for LKE clusters

I have a requirement to create node balancer per namespace. For some reason creating an ingress does not create a new node balancer for second namespace. It worked fine for the first namespace.

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
name: abc
annotations:
kubernetes.io/ingress.class: nginx
cert-manager.io/cluster-issuer: "letsencrypt-prod"
spec:
tls:

• hosts:
  • example.com
    secretName: example-tls
    rules:
• host: example.com http: paths:
  • backend:
    serviceName: servicename
    servicePort: 80

Any suggestion's or ideas on how I can fix this issue
