Push notification doesn't work for Passbook from C#

Question

I am trying to achieve Apple Push notification for Passbook from C#. I am not getting any error or exception but the notification is not received on device.

Following are steps already taken
- I am trying it with production pass p12 certificate which I am using for Pass signing
- I am having my tcp port 2196 open as required by APNS
- I am sending empty Json payload and push token (which I am receiving from passbook when user adds pass to passbook and our service is invoked)

When I am trying to read response from the SSLstream I am getting it as \b\a\0\0\0\0

Any help will be great help. Thanks!

First, ensure you're using the right endpoint APNS endpoint. Second, are you seeing anything in the iPhone logs of the device you're pushing to? — Tomas McGuinness
Is your webServiceURL receiving a request for serials and is it responding appropriately? Is this request followed by a second request to receive the updated .pkpass bundle? Is the updated .pkpass bundle different to the original bundle? Is a changeMessage set for the value that has changed, and does this message contain %@? You are developing in C# and so may not have access to Xcode for debugging - if so and if your webServiceURL is a public URL, if you can post a link to the .pkpass bundle, we can help diagnose for you. — PassKit
@PassKit - I have all web services in place so when I am trying pull to update my getpass service is invoked and pass is updated, I can see that through device logs. Both the bundles are same as there is no change in pass content, my requirement is I need to show a push notification to user with some message in notification after 7 days of pass installation. I dont have changemessage field in pass.json. Do I need to add changeMessage? Wont it work without it? — Asif Mukhida
@tomasmcguinness - I am pointing to gateway.push.apple.com and port 2195. Mostly nothing is coming through still I will confirm it again and update here. — Asif Mukhida

You DO need a changeMessage if you want anything to show on the lockscreen, but you could also consider a relevantDate alert if it is always after 7 days. The following answer details all of the mandatory requirements to invoke a lock screen message from a push to a pass. How to make a push notification for a pass.

Specifically note point 5:

alert, badge, sound and custom property keys are all ignored - the push's only purpose is to notify Passbook that your web service has a fresh pass. The notification text will be determined by the changeMessage key in pass.json and the differences between the old and the new .pkpass bundles
