gRPC calls not working with sidecars when Kubernetes Service maps two ports to same targerPort of destination Pod

Hi everyone,

I need help from the community on a problem that we have with gRPC calls that are failing with sidecars enabled.

I’ve reported all the relevant infos in this github issue: gRPC calls not working with sidecars when Kubernetes Service maps two ports to same targerPort of destination Pod · Issue #33379 · istio/istio · GitHub

Thank you very much
