Ionic CLI didn’t forward dev server port

Hi, from the documentation at Live Reload - Ionic Documentation, it will forward the port automatically. However, when running the command

ionic cordova run android -l

then inspect through chrome browser, it only uses localhost without port.

Tried passed in configuration such as

ionic cordova run android -l —configuration aws

yet still showing localhost in chrome dev console.

Is there anyway other configuration might have caused this behaviour? Thanks
