title: Kubernetes ingress "an error on the server ("") has prevented the request from succeeding"
body: <p>I have a managed azure cluster (AKS) with nginx ingress in it.
  It was working fine but now nginx ingress stopped:</p>
  <pre><code># kubectl -v=7 logs nginx-ingress-&lt;pod-hash&gt; -n nginx-ingress
  GET https://&lt;PRIVATE-IP-SVC-Kubernetes&gt;:443/version?timeout=32s
  I1205 16:59:31.791773       9 round_trippers.go:423] Request Headers:
  I1205 16:59:31.791779       9 round_trippers.go:426]     Accept: application/json, */*
  Unexpected error discovering Kubernetes version (attempt 2): an error on the server (&quot;&quot;) has prevented the request from succeeding

  <pre><code># kubectl describe svc kubernetes

  <p>When I tried to <code>curl https://PRIVATE-IP-SVC-Kubernetes:443/version?timeout=32s</code>, I've always seen the same output:</p>
  <p><code>curl: (35) SSL connect error</code></p>
