After our iPods stopped receiving updates for new app versions for Epic Rover app, it was determined that the FW was blocking that port. Upon further troubleshooting, it was determine that the change in the URL for the apps that used to be itunes.apple.com has changed to apps.apple.com. The new URL, apps.apple.com, was not whitelisted in Blue Coat. Apple stated that they try to update the TCP Ports list document in support.apple.com, but sometimes, new ports are not listed. The request may come down to the device, but when the device is trying to reach the new URL, the connection is blocked. I knew there was nothing wrong with the device, with the VPP token or Apple's back end. Try it from a hotspot or any other non-firewall, web-content filtered SSID.
