Not able to run simple code on IE11 on a node using GRID

Hi Guys,

I am unable to run a simple code using GRID for IE 11 browser, however i am able to run IE11 browser easily on my local machine. I have set protected modes disabled for internet security section which is a pre requisite when working with IE 11.

Please note that i was able to successfully set up a hub and a node.

Thanks in advance
