Answer 1

Please check the settings with the step IIS Web App Manage. Seems you did not set the Virtual path correctly.

Virtual path:

Parameters for IIS Application configuration:

Enter the virtual path in IIS relative to the parent website. The parent website must already exist. Example: to create an application named Site/Application enter /Application.

Parameters for IIS Virtual Directory configuration：

Enter the virtual path in IIS relative to the parent website. The parent website and application must already exist. Example: to create a virtual directory named Site/Application/VDir enter /Application/Vdir.

See Deploy: IIS Web App Manage for details.
