I too am getting the following in my console logs when filtering on APNB.
My push notification was working on my new install of Server 10.7.3 but now is not working at all. Not sure if it was my recent update from Server 10.7.3 to Server 10.7.4 that caused the break or not. When I add an IMAP, CalDAV oeCardDAV account to my iOS devices it shows that Push is available, however, push notifications DO NOT work.
NOTE: My server is kept in a data centre. All inbound traffic to the server's public IP are forwarded to the server's private IP. All required ports for APNS are open and configured correctly in Lion Server firewall service. I have even tried turning off firewall service to no avail, therefore can rule out firewall config as the problem.
