git pull fails with "Either the application has not called WSAStartup, or WSAStartup failed" : <p>I have just installed Windows 10, Visual Studio Community 2015, and <a href="https://git-scm.com/download/win" rel="noreferrer">Git for Windows</a>. I also installed the latest Bitbucket and GitHub extensions.</p>

<p>Within Visual Studio I cloned my Bitbucket.com-hosted repository, and performed these operations successfully:</p>

<pre><code>$ git --version
git version 2.19.2.windows.1

$ git pull
Already up to date.
</code></pre>

<p>But then when I tried to pull from another repository I got this error:</p>

<pre><code>$ git pull git://github.com/aegif/CmisSync.git
fatal: unable to lookup github.com (port 9418) (Either the application has not called WSAStartup, or WSAStartup failed. )
</code></pre>

<p>I am able to ping github.com though.</p>

<p>How can I investigate and fix the problem?</p>
