Istio 1.6.7 : VM based Proxy Not Working

We are trying to enroll a CentOS7 VM into existing service mesh using the doc - https://istio.io/latest/docs/examples/virtual-machines/single-network/

Getting into - external/envoy/source/common/config/grpc_subscription_impl.cc:101] gRPC config for type.googleapis.com/envoy.api.v2.Listener rejected: Error adding/updating listener(s) 172.20.74.114_8080: Didn’t find a registered implementation for name: ‘istio.alpn’

THE proxy-status return LDS as stale , and RDS as not sent , while CDS is synced.

Any pointers on the issues?
