title: NodePort service of istio-ingressgateway returns connection refused
body: <p>I have deployed istio in kubernetes through the official helm chart, but cannot access the nodeport service of the istio-ingressgateway. I get connection refused.</p>
  
  <p>There is a listener on NodePort 31380 though.</p>
  
  <pre><code>$ netstat -plan | grep 31380
  tcp6       0      0 :::31380                :::*                    LISTEN      8523/kube-proxy
  </code></pre>
  
  <p>The iptables firewall on this k8s node does not block the traffic to 31380/tcp.</p>
  
  <p>I tried connecting to 127.0.0.1:31380 and the LAN IP of the node directly from the node.</p>
  
  <p>Any ideas what could be wrong or how I can debug that?</p>
  
  <p>Best regards,
