title: What kind of network error is Chrome encountering when 'Status = (failed)' or 'Status = (canceled)'
body: <p>I'm trying to send requests to google ads server and openx but they fails in the browser and I cant figure out why. There are times that the requests pass but most of the time they fails. The behaviour is random and I cant understand why they fails sometime. I run this in clean browser with no extensions (like Ad blocker etc.)</p>
  
  <p>This is how the output in my chrome network tab looks like:</p>
  
  <pre><code>Name    Method  Status      Type                Initiator   Size    Time
