Angular 2 http service. Get detailed error information : <p>Executing Angular2 http call to the offline server doesn't provide much info in it's "error response" object I'm getting in the Observable's .catch(error) operator or subscription error delegate (they are both share the same info actually). But as you can see on the screen shot of the console there's actual error was displayed by zone.js somehow.
So, how can I get this specific error info (net::ERR_CONNECTION_REFUSED)?</p>

<p>Thanks.<a href="https://i.stack.imgur.com/tLrA0.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/tLrA0.jpg" alt="enter image description here"></a></p>
