APNS deprecated for new pass type ids?

Hi,

We are currently using the deprecated APNS service (ssl://gateway.push.apple.com:2195) which is working fine for our existing passes. For one of our clients we had to create a new Pass Type ID + certificate. The new ID + certificate is working fine for creating, adding and removing passes but the APNS service is not working for some reason which makes it unable for us to automatically update a pass. Neither are we getting an error when connecting to the APNS service. The push is sent to the device without error but the pass never gets back to the server to retrieve the updated pass.

Does the deprecated APNS service no long work for new passes? It still works fine for our existing pass type ID and certificate but we can't make it work for new passes for some reason...

Thanks in advance.
