Dashboard is not working in IE 11

I hosted the Dashboard on IIS, it is working in Chrome but not on IE. Is there any setting i need to turn on? I use IE 11

if I put like below it works in IE

if put the hostname it comes blanks - > http://Server01/home

if i put ip address it works in IE
I think it is DNS issue. Sorry and I will fix it

IE 11 dont support WebSockets.
So for most part of UD, IE 11 will not work.
