Collect your analytics data into two or more Piwik servers

I followed the example below to send data to 2nd Piwik server and I am not getting anything on the 2nd Piwik server. Data is coming on the 1st Piwik Server. Assume my 2nd Piwik running on separate IP is https://analytics.example.com/piwik.php in the sample config below. What have I done wrong? Help needed.

The example below shows how to use addTracker method to track the same analytics data into a second Piwik server. The main Piwik server is piwik.example.org/piwik.php where the data is stored into website ID 1. The second Piwik server is analytics.example.com/piwik.php where the data is stored into website ID 77.
