I am sending an HTTP POST API request to my IIS web server with the address localhost/support/api/tickets.json. It works fine on APACHE but on the IIS server I am getting a 404 error. Any suggestion?

PHP version: 5.3.27

IIS Version: 7

Operating System: Windows Server 2008 R2

OSTicket Version: 1.7.3

ISS error log:
