<p>I am using Istio-1.0.6 to implement Authentication/Authorization. I am attempting to use Jason Web Tokens (JWT). I followed most of the examples from the documentation but I am not getting the expected outcome. Here are my settings:</p>

<p>Service</p>

<pre><code>kubectl describe services hello

<p>Virtual Service</p>

</code></pre>

<p>Policy</p>

<pre><code>kubectl describe policies

</code></pre>

<p>RESULT</p>

<p>I am expecting to get a 401 error but I am getting a 200. What is wrong with my configuration and how do I fix this?</p>

<pre><code>curl $INGRESS_HOST/hello -s -o /dev/null -w "%{http_code}\n"
200
</code></pre>

<p>You have:</p>

<pre><code>Port:              &lt;unset&gt;  8080/TCP
</code></pre>

<p>For <em>Istio routing and security</em>, you must set the port name to <code>http</code> or <code>http-&lt;something&gt;</code>.</p>

<p>I tried with Istio 1.1. I got a <code>503</code> rather than a <code>401</code>.</p>
