Is it reproducible with the free download version from? https://www.scirra.com/
yes it is! Unfortunately that version doesnt allow to set up a custom local host address. It uses localhost (127.0.0.1) by default, which I think you can set up in /etc/hosts if you want it to be different.
You still get the httpapi stub messages in terminal and it still fails to launch a web browser or even try to start the game - due to failed hosting.
