gspread/ httplib2 SSLHandshakeError
<p>I had gspread for python working, but after about a month I started getting the following error:</p>

<pre><code>gc = gspread.authorize(credentials)
</code></pre>

<p>I have tried everything I can think of, including installing a new python distribution, but nothing works. I am on a mac, I have upgraded pyOpenSSL and done everything I can think of. Does anyone have an idea?</p>
