it seems you lose the connection during the push notification, and yes you should add the path make sure you double check that the port your using is correct and open.

Also note that Push notification is also not always guaranteed. You can refer 'More about Push notification' section in https://developer.apple.com/library/ios/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Chapters/WhatAreRemoteNotif.html

Quality of Service

Apple Push Notification Service includes a default Quality of Service (QoS) component that
performs a store-and-forward function. If APNs attempts to deliver a notification but the device 
is offline, the QoS stores the notification. It retains only one notification per application 
on a device: the last notification received from a provider for that application. 
When the offline device later reconnects, the QoS forwards the stored notification to the device.
The QoS retains a notification for a limited period before deleting it.

If a device is offline (either turned off or just unreachable) then it will receive at most a single push notification you attempt to send to your application during that time.
