Http.sys application prompt HttpSendHttpResponse failed

I tested it without your virtual host names (Because I can't use them anyway) and it worked as expected using latest version 15.5.2

I suspect that it is something related to your bindings. Can be also related to the machine itself (have you tested in more than 1 Windows version?)

I'll need more time to find out what's wrong with it....
