title: Connection refused when attempting to connect the docker URL
body: <p>I have confirmed that alpine/socat is running on <a href="http://127.0.0.1:2376/" rel="nofollow noreferrer">http://127.0.0.1:2376/</a>
  Potentially an issue with daemon not being connected, help would be greatly appreciated. TIA
  Using OSX</p>
