title: Resharper Extension Manager is empty
body: <p>I'm working with VS2103 Update 5 and RS 10, the feed for the extensions is <a href="https://resharper-plugins.jetbrains.com/api/v2/curated-feeds/Wave_v3.0/" rel="nofollow noreferrer">https://resharper-plugins.jetbrains.com/api/v2/curated-feeds/Wave_v3.0/</a> and also tried changing https to http.</p>
  
  <p>any time I open Resharper Extensions Manager, I get the extensions window blank and nothing loads.</p>

  <p>I'm working under a proxy, but all of my teammates have the same proxy configuration and I'm the only one that have this issue. I used fiddler to check the request, but no request is made at all.</p>
  
  <p>Not sure if VS is blocking something or what's happening, but I've tried many things like updating to VS2015, uninstall and reinstall RS, downgrade RS from 10 to 9.2.</p>
  
  <p>you have any idea of what could be happening here?</p>
