Answer 2

If you're requiring Forms Authentication, but that module isn't running, IIS just gives a 403 error because it can't get you the kind of authentication the application requires.

So you can try is setting the "Run All Managed Modules for All Requests" option under in your applicaiton's Web.config

<system.webServer>
    <modules runAllManagedModulesForAllRequests="true"></modules>
    <handlers>
      <remove name="UrlRoutingHandler"/>
    </handlers>
  </system.webServer>

Answer 3

You can check if the folder where you're publishing the APP have permissions to IIS. You can try to give permission to "everyone" in the security property of the folder.

If not, check the web.config of the WebAPI on the ISS and double check the auth values and configuration.
