title: WSO2 APi Manager Response Code 0
body: <p>I'm trying to use WSO2 API Manager 1.10.0 on an existent micro-services project with REST APIs following WSO2 tutorial.</p>
  
  <p>I have installed it on my computer as well as a copy of my application and configured AM to manage requests (GET, POST and DELETE) to my resource but I always obtain a "Response code 0" with Response Header</p>
  
  <pre><code>{
     "error": "no response from server"
  }
  </code></pre>
  
  <p>Trying to contact my application using Advanced REST Client I obtain 200 with the correct result.</p>
  
  <p>My APIs use a token inside the header to authenticate the user passed so I have implemented a dummy API without authentication but I still have the same issue.</p>
  
  <p>I have tried also the Cloud version with our test server but still obtaining the same result. 
  I found this guide <a href="http://wso2.com/blogs/cloud/video-setting-up-custom-url-for-api-store-and-gateway/" rel="nofollow">http://wso2.com/blogs/cloud/video-setting-up-custom-url-for-api-store-and-gateway/</a> but I don't know if this can be a solution for the problem in localhost.</p>
