Modify the existing Istio Gateway from the previous project, istio-gateway.yaml. Currently I have a one single node RKE cluster (which have all 3 controleplane, etcd & worker in the same node (EC2 instance)), @siddharth25pandey you will have ingress gateway as Load balancer with external ip (x.x.x.x) in istio-system namespace with 80 and 443 ports open, after that you will have Gateway which has port 80 and 443 opened for a particular domain name /host and virtual service connects with gateway to pass it to your application port, this is the flow, @siddharth25pandey below is the troubleshooting guide for Metallb, can you Curl or ping the load balancer ip inside the cluster and see if you are able to access your application, if you can access it then it is definitely issue with your L2Advertisement and IPAddressPool, https://metallb.universe.tf/configuration/troubleshooting/.

Issue was really simple and silly. This is a quick but not so cool way to set up SSL certificate for any LoadBalancer or Ingress that you may be working with. Similar to the ingress gateway configuration, aGatewayresource must be created that will be a bridge between Istio configuration resources and the deployment of a matching gateway. Another way of tackling this potential issue is to have separate load balancer configurations with, for example, different port level settings. (1 ), ( ) : ( ) .
