I testing the K3000 product and it seems to work great with an Adroid device, but it does not work well with iOS.

I tried multiple time recreating SSL cert, apple push cert, wiping an iPad to have a clean start. nothing seems to work

Often this occurs when APNS ports are not open on the firewall. Please review the port requirements below and/or check your firewall for error logs regarding these ports.


 For APNs traffic to get past your firewall, you'll need to open these ports:

  • TCP port 5223 (used by devices to communicate to the APNs servers) 
  • TCP port 2195 (used to send notifications to the APNs)
  • TCP port 2196 (used by the APNs feedback service)
  • TCP Port 443 (used as a fallback on Wi-fi only, when devices are unable to communicate to APNs on port 5223)

The APNs servers use load balancing. Your devices will not always connect to the same public IP address for notifications. The entire address block is assigned to Apple, so it's best to allow this range in your firewall settings.
