Dynamics GP 2015 R2 Web Client Install A problem occurred creating a session

I am receiving the below error when trying to run the web client on a new web client installation.  I receive this error after logging into the GP Web Client using IE 11.  I checked the Event Viewer and it says the same thing plus check the Central Session Service logs but that folder is empty.

This is an internal single server deployment, running web client on the server.
