Can not grpc server with upstream connect error or disconnect/reset before headers. reset reason: connection failure, transport failure reason: delayed connect error: 111","grpc_status":14}

I have deployed one grpc server to the k8s in docker desktop and used istio as external LoadBalancer…
But I can not send request the grpc server… I tried istio gateway+virtual service and istio ingress controller + k8s ingress.
All get the same error. But if using port-forward to the service and access directly, it works.
Do you have any advise? Thanks

istioctl version
client version: 1.14.1
control plane version: 1.14.1
data plane version: 1.14.1 (3 proxies)

kubectl version --short
Flag --short has been deprecated, and will be removed in the future. The --short output will become the default.
Client Version: v1.24.2

My bad. It’s bug in my image
