Dial tcp 127.0.0.1:15000: connect: connection refused

Hi

I am trying to set up Istio Ingress Gateway(Istio v1.1) on a GKE cluster(1.11.8-gke.6) on GCP. The logs show the following error

2019-05-20T23:21:38.274775Z info Envoy proxy is NOT ready: failed retrieving Envoy stats: Get http://127.0.0.1:15000/stats?usedonly: dial tcp 127.0.0.1:15000: connect: connection refused

Looking at the ports listening using netstat I see only the following port

tcp6 0 0 :::15020 ::: LISTEN*

Can someone please help on this error?

Having similar issue and the field starts to be increasing overtime until container restarts. The info usually comes after segmentation fault:

Caught Segmentation fault, suspect faulting address 0x0
