I have running couple of microservices with grpc protocol in k8s, it is connecting outside thought networking loadbalancer , right now i am using a envoy system in front of NLB
(Envoy > NLB > grpc service).
Application API es are working fine using envoy ip and port number , right now i need to use ssl for Envoy , I have trying to add ssl conf in envoy configuration file but getting error like below, butit is working fine without ssl conf.
ubuntu 18
envoy version 1.18.2
