When ever we are trying to access site via dispatcher userProperties is always becoming null. So we tried giving a null check page is loading with an alert "Your request could not be completed because you have been signed out." and a string /?resource=%2F%3Fresource%3D%252F is getting appended to URL always.
But when ever we are trying to access the site using IPs, it is loading without any exception and userProperties is no null.
