fly execute on localhost fails
<p>I have a simple task that I want to execute on my local concourse instance:</p>

<p><strong>build-frontend.yml</strong></p>

<pre><code>---
platform: linux

image_resource:
  type: docker-image
  source:
    repository: node
    tag: 'latest'

inputs:
- name: client-devops

run:
  path: client-devops/scripts/test
</code></pre>

<p>the task is executed:</p>

<pre><code>client-devops daka$ fly -t frontend execute --config build-frontend.yml
executing build 1

exit status 2
</code></pre>

<p>The target is available:</p>

<pre><code>client-devops daka$ fly targets
name          url                         expiry                       
frontend      http://127.0.0.1:8080       Fri, 11 Nov 2016 09:13:55 UTC
</code></pre>

<p>Why does it say can't connect to localhost, I can connect to the UI from my browser?</p>
