I have installed istio ingress in my EKS cluster. Istio ingress agent is started and agent is running in other configured ports but it is missing in port 8080.

here is the status of ports listed.

istio-proxy@istio-ingressgateway-7bfd767877-4fk72:/$ netstat -tunlp

The same ingress I deployed in kops based cluster and it works.

Also when i looked envoy start command it looks same.
