title: Rails / Error Bundler::HTTPError during request to dependency API
body: <p>I have a cms engine that I created not long back, I have used it many times with no problems. But as of today I keep getting this error when trying to update the engine/gem or if I push it to Heroku. </p>
  
  <p>This is the error I get: </p>
  
  <pre><code>Error Bundler::HTTPError during request to dependency API
  </code></pre>
  
  <p>I know that the Rubygems "Dependency API" has been down over the last couple of days. But it should be up again. How can I troubleshoot this error further and determin whether this is a problem on my side or with Rubygems?</p>
