My notification listener runs on port 81 but none of  my subsribed notifications are delivered to my listener.  GetNotificationsUsage reports the following exception: for those failed notifications : com.ebay.kernel.service.invocation.client.exception.ConnectionTimeoutException.  

 What is the problem?

Detailed Description 

  The possible cause for getting the com.ebay.kernel.service.invocation.client.exception.ConnectionTimeoutException when runs Notification listener on port 81 is that the 81 is a non-standard port which is blocked by the eBay firewall and/or ISP (Internet Service Provider).

  The workaround or fix for this issue is to reconfigure your Platform Notification listener and host it on port 80.
