title: Can't read from file issue in Swagger UI
body: <p>I have incorporated <code>swagger-ui</code> in my application.</p>
  <p>When I try and see the <code>swagger-ui</code> I get the documentation of the API nicely but after some time it shows some error icon at the button.</p>
  <p>The Error message is like below:</p>
  <blockquote>
  <p>[{&quot;level&quot;:&quot;error&quot;,&quot;message&quot;:&quot;Can't read from file
  http://MYIP/swagger/docs/v1&quot;}]</p>
  </blockquote>
  <p>I am not sure what is causing it. If I refresh it works and shows error after few seconds.</p>
