title: Getting Unknown error in charles during inspecting api websocket of an android app
body: <p>Hey Some Days ago am working with charles nd its working properly but now i am unable to use it, it shows me unknown. I tried with 2 android (android pie) &amp; 1 android emulator (android lollipop including root). I tried with all network security config below: </p>
  
  <p>1) Given on Charles Official website</p>
  
  <pre><code>&lt;network-security-config&gt; 
    &lt;debug-overrides&gt; 
      &lt;trust-anchors&gt; 
        &lt;!-- Trust user added CAs while debuggable only --&gt;
        &lt;certificates src="user" /&gt; 
      &lt;/trust-anchors&gt; 
    &lt;/debug-overrides&gt; 
  &lt;/network-security-config&gt;
  </code></pre>
  
  <p>2) From other sources</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;network-security-config&gt;
      &lt;base-config&gt;
          &lt;trust-anchors&gt;
              &lt;certificates src="system" /&gt;
          &lt;/trust-anchors&gt;
      &lt;/base-config&gt;
      &lt;debug-overrides&gt;
          &lt;trust-anchors&gt;
              &lt;certificates src="user" /&gt;
          &lt;/trust-anchors&gt;
      &lt;/debug-overrides&gt;
  &lt;/network-security-config&gt;
  </code></pre>
  
  <p>I was using 2nd network security config when its working properly. Is there any solution or alternative method to inspect the responses and websockets inside the app.</p>
