title: Enterprise app deployment doesn't work on iOS 7.1
body: <p>We distribute apps via an Enterprise account, using an <code>itms-services://</code> URL. This has always worked fine, but after installing the iOS 7.1 beta on our iPad it refuses to install. Instead we just get the generic <code>Cannot connect to example.com</code> message that iOS unhelpfully displays when there is any sort of problem downloading the app.</p>
  
  <p>I've been unable to find anything here on SO, on Google or in the 7.1 release notes to suggest what could be causing the problem.</p>
