IIS DNS Lookup for “XYZ” failed. System.Net.Sockets.SocketException This host is unknown

Question

I have strange issue with IIS on my local machine. IIS can't resolve host that bind to some specific name to 80 port. I have web site that bind to XYZ name and 80 port nothing special, this XYZ name is present in host file as well. it is no any information in IIS log, but if open web site with fiddler I see an error

[Fiddler] DNS Lookup for "XYZ" failed. System.Net.Sockets.SocketException host is unknown

without fidler just next message

This webpage is not available ERR_NAME_NOT_RESOLVED

default web site with localhost name iis can open easily.
