title: VS 2017 Pull operation failed
body: <p>I went to do a <code>sync</code> in VS 2017 (15.3.5) Team explorer and it says <code>pull</code> operation failed. I am using <code>git</code> as version control.</p>
  <p>This is the error I got:</p>
  <pre><code>Remote: Microsoft (R) Visual Studio (R) Team Services        
  Remote: 
  Remote: Found 18 objects to send. (631 ms)        
  Pull operation failed.*
  </code></pre>
  <p>I've tried several things:</p>
  <ol>
  <li>Delete the branch and checkout again.</li>
  <li>Connect to team system again.</li>
  </ol>
  <p>Nothing works. expecting expert advice.</p>
