title: Docker: An error occurred trying to connect
body: <p>Installed Docker on Windows with 2 additional installs, Oracle VM VirualBox and Kitematic. I've disabled Hyper-V in my Windows 10 PC. Now the problem is I can't download any Docker images from DockerHub, not even I can run the command as</p>
  
  <pre><code>Docker info
  </code></pre>
  
  <p>At both ends it shows the following error.</p>
  
  <blockquote>
    <p>An error occurred trying to connect: Get
    <a href="http://localhost:2375/v1.21/info">http://localhost:2375/v1.21/info</a>: dial tcp 127.0.0.1:2375: ConnectEx
    tcp: No connection could be made because the target machine actively
    refused it.</p>

  <p>If I run it in Docker QuickStart Terminal it works, but not working in PowerShell or in MSBuild.</p>
