Q: OS X Server: Push Notifications doesn't work

Hello

We running about 30 pcs OS X Server (10.8 to 10.10). I configurated on all system the Notification with my Apple ID, but when something goes wrong I never get an notification. All of them have an unique Apple ID. The Apple ID is working, as soon as I renew it I get instandly an Apple to the E-Mail-Adress connected to the Apple ID

We need that info, to see if we could expect problems on our servers. Any other Person who have the same problems? I found nothing that their should be an issue with the notification, but strange it that is doesn't work on all our Server

Regards

Gérard
