title: SKPayment / SKPaymentQueue: Cannot connect to iTunes Store
body: <p>I am building an App with IAP (auto-renewal subscription). The workflow seems to work fine, IPA are created for sure (in iTunes connect), sandbox user also logged in. The IAP product ID is also correct but I get the error (from <code>SKPaymentTransaction</code>):</p>
  
  <p><code>Error Domain=SKErrorDomain Code=0 "Cannot connect to iTunes Store"</code></p>
  
  <p>Before that error I get the purchase screens where the price, the duration of the subscription and the name of the subscription is displayed. So the connection and the product ID is correct.</p>
  
  <p>I am logged in with sandbox user: The screens displays <code>[Environment: Sandbox]</code>. </p>
  
  <p>I am using a real device (iPhone 7 and iPhone 5). The error occurs on both devices and on simulator (for sure on simulator?).</p>
  
  <p>Any ideas?</p>
