Philips DS1155/12 not recognized by iPhone 5

I buyed the Philips DS1155/12 docking station about one year ago from Amazon Italy. I don't have any problem with the lightning connector of the docking station with my iPhone 5 until i have iOS 8. When I upgrade my iPhone 5 to iOS 9 (9.0.2 at first and now I have the same problem with the latest iOS version) , my device say the lightning connector of the docking station is not certified for use with iPhone and I cannot use at all my docking station. I tested the docking by plugging via USB another device (for instance my e-reader) and the docking station work properly recharging the battery of the device. I've also open a ticket to Philips Assistance Forums but they ask to me to open a ticket here because "apparently" the problem is something related to Apple and iOS 9. Last but not least, the Philips DS1155/12 is certified by Philips for use with iPhone 5.
