Communicator needs to append a port to the backendURL also if the request is to be sent inside the local network, not only when it's on your own development device. For example to check the page on the phone.

Of course this addition of the port to the backendURL can be omitted

be available at an address without an explicit port, but a lot of people
simply won't do this.
