As Apple's Documentation:

Cannot connect to iTunes Store The "Cannot connect to iTunes Store" issue may be due to one or more of the following reasons:

1. The sandbox may be unreachable.
2. Your app does not have a bundle version (CFBundleVersion). See Setting the Version Number and Build String for more information.
3. Your app is running in the Simulator, which does not support in-app purchase.
4. You are attempting to purchase a product that is unavailable for sale. See Query the App Store for product information before presenting your app’s store UI for more information.
