Hello,
Kubernetes 1.15.6
Istio 1.2.5
I have a client outside of Kubernetes cluster making a HTTP/1.0 request to a service running in Kubernetes. The service is pointing at pods with istio-proxy sidecars. I made the following config changes and I am still getting a 426 HTTP code in response.
I added the environment variable
ISTIO_META_HTTP10=1 to istio-ingressgateway as recommended here: https://github.com/istio/istio/issues/13085#issuecomment-557754573
PILOT_HTTP10=1 to istio-pilot. Ref: https://istio.io/docs/reference/commands/pilot-agent/
