WebViewer Can't Access and Load HTML File (in standard emulator)

I've found an old post that apparently updates the old tutorial I was referencing. I followed it exactly and it still doesn't work. I keep getting the "Could not connect to the server" error. I'm including the project I've created. If somebody doesn't mind, please import the project and test it for yourself.
