Istio Ingress-Gateway Always Stale

Whenever I redeploy, the istio-ingressgateway is always in a stale state. I have not been able to successfully get ingress into a fully synced state. I am using the most up to date helm charts and am running v1.1.5 docker images. I am not sure how to get ingress into a fully ready state.

istio-ingressgateway-<uid>.istio-system SYNCED STALE (Never Acknowledged) SYNCED (100%) SYNCED istio-pilot-<uid> 1.1.3

I have ingress SDS enabled and sporadically I also encounter the error:
error SDS grpc server for ingress gateway proxy failed to start: accept unix /var/run/ingress_gateway/sds: use of closed network connection.

I have see a few issues opened that reference the closed network connection but I have not been able to identity this error in the Istio code?

Iā€™m running k8s verision v1.13.6-gke.13 and istio 1.2.2

I saw a similar behaviour when i have a headless service called redis. I deleted the redis service and everything goes fine.

Do you have Ingress SDS enabled?

No, SDS is disabled.
