title: Cannot authenticate in Visual Studio 2017
body: <p>My Visual Studio 2017 trial period has expired, and I am unable to log in to unlock the program. Authentication fails every time, with the error:</p>
  
  <pre><code>An error has occurred and we can no longer retrieve information for your account. 
  Please reenter your credentials.
  </code></pre>
  
  <p>I checked the logs for the <code>servicehub</code>, and they all say (line breaks added for readability):</p>
  
  <pre><code>Error : 
    Error starting hub controller: 
      System.InvalidOperationException:
        Controller terminated before accepting connections.
          Exit code: -1073741502.
  </code></pre>
  
  <p>or</p>
  
  <pre><code>Error : 
    Exception retrying connect to json rpc: 
      System.InvalidOperationException: 
        Controller terminated before accepting connections.
          Exit code: -1073741502.
  </code></pre>
  
  <p>I have tried running the program as an administrator, deleting the session tokens, using different Microsoft accounts, and even using different PCs. The different PCs issue makes me think that it could be some problem with my network, but I'm not sure what that could be.</p>
