Unable to access Dispatcher end url from AEM screen Player

[bhaskaran_govin]

We are trying to integrate the Dispatcher end from AEM screen player, but we are getting the 

AEM Screen Blank Page.  How do configure the dispatcher end. We are not able to find dispatcher end point URL integration steps. Can you please suggest in this.

I have followed the below docs.
