Issue while running GRPC in embedded mode with spring boot #1

I am trying to deploy my application [ GRPC + Spring Boot ] in Kubernetes infra.

I have set up a GRPC server with Spring boot on our pods - and as suggested I am running the processes on 2 different ports [ GRPC (port - 8443)+ Spring Boot (port- 8080) ] but my VIP is pointing to port 8443 right now.

I am able to configure SSL using .useTransportSecurity in a standalone grpc server (standalone here I mean without spring boot)

Problem: If my VIP is pointing to the GRPC server process on the pods I need to offload SSL in GRPC server but I do not see details how to do that if I am running my grpc server as an embedded server with spring boot.

Even if I deploy the application and when I try to connect using GRPC client I am seeing below error in servers and clinet is getting disconnected.

Where can I find additional application.properties specific to grpc ? I could only find grpc.server.port, grpc.server.host

The error above is in server side while I do see below error at client side -
