title: Confused about Alamofire sessionmanager
body: <p>Using Alamofire 4.0 and Swift 3.0 this works:</p>
  
  <pre><code>Alamofire.request("http://content.uplynk.com/player/assetinfo/ab19f0dc98dc4b7dbfcf88fa223a6c3b.json", method: .get).responseJSON {
  (response) -&gt; Void in
  print("Success: \(response.result)")
  }
  </code></pre>
  
  <blockquote>
    <p>Success: SUCCESS</p>
  </blockquote>
  
  <p>However when I try to use the Sessionmanager so I can include a timeoutInterval, my requests always fail</p>
  
  <pre><code>let configuration = URLSessionConfiguration.default
  configuration.timeoutIntervalForRequest = 15
  let alamofireManager = Alamofire.SessionManager(configuration: configuration)   
  alamofireManager.request("http://content.uplynk.com/player/assetinfo/ab19f0dc98dc4b7dbfcf88fa223a6c3b.json").validate().responseJSON { 
      response in
      print("Success: \(response.result)")
      print("Response String: \(response.result.value)")
  }
  </code></pre>
  
  <blockquote>
    <p>Success: FAILURE</p>
  </blockquote>
  
  <p>Would be grateful if someone could help point me in the right direction here.</p>
