browser-sync cannot proxy https-websites
<p>I use <a href="https://www.browsersync.io/" rel="noreferrer">browser-sync</a> 2.11.1 with OS X Chrome 48.0.2564.97 (64-bit)</p>

<p>When I use it as a proxy for http-website:</p>

<p><code>browser-sync start --proxy http://example.com</code></p>

<p>it works great and I can point multiple browsers to localhost:3000 so that actions done in one of them are replicated in others.</p>

<p>However when I use it for https-website:</p>

<p><code>browser-sync start --proxy https://twitter.com</code></p>

<p>it doesn't work. When I point browsers to localhost:3000 they do not show up in "Current Connections" of browser-sync UI and also the actions are not replicated between them.</p>

<p>Maybe it has something to do with my browser complaining about https:

<p>Is there a bug in browser-sync or am I missing something?</p>
