I have configured EKS 1.23 and installed our product's containers and also configured the ISTIO service mesh for secure communication between containers. We are running some WEB containers and some Backend containers. Inside the backend containers, we make an EJB invocation using JBoss-client. Here when we are using the container IP or POD name then EJB invocation is happening successfully but whenever we use the container's service name or service IP then it says 'Please check if the client and server are configured to use the same protocol and ports.'. And if I check the istio-proxy access log then getting below error message:
[2023-01-24T06:04:03.982Z] "GET / HTTP/1.1" 403 - upgrade_failed - "-" 0 0 0 - "-" "-" "89bbb561-d061-4a17-895e-bb3503e9e7b3" "omsejb:8080" "-" outbound|8080||omsejb.servicemesh.svc.cluster.local - 172.20.92.13:8080 10.0.2.252:43628
I tried to troubleshoot but somehow could not find any trace. It would be helpful if someone can support.
