Worklight error when sending push notification

I am trying to use Worklight push notification to send push for a iOS+Android Application.

I created the submitNotification function in my adapter, and when I invoke it, it says that the push was sent successfully, but in reality, I have no push received in my device.

When I see the logs I can read:

then

 Failed to send message com.notnoop.apns.EnhancedApnsNotification@96eee2c0... trying again

My submitNotification function :

function submitNotification(userId, notificationText) {
    var userSubscription = WL.Server.getUserNotificationSubscription(
            'myAdapter.MyPushEventSource', userId);

    if (userSubscription == null) {
        return {
            result : "No subscription found for user :: " + userId
        };
    }

    WL.Logger.debug("submitNotification >> userId :: " + userId + ", text :: "
            + notificationText);

    WL.Server.notifyAllDevices(userSubscription, {
        badge : 1,
        activateButtonLabel : "Open",
        alert : notificationText
    });

    return {
        result : "Notification sent to user :: " + userId
    };
}

Is there something wrong with my code? or with my Network ?

It was finally a network issue.

We changed our Firewall configuration to allow access to Google and Apple push servers. For Apple Servers, you can find more details at this address : http://developer.apple.com/library/ios/#technotes/tn2265/_index.html#//apple_ref/doc/uid/DTS40010376-CH1-TNTAG41
