Ionic v4 livereload on Android emulator not working

I want to test my Ionic 4 app on the Android emulator with live-reload, but when I run it, the emulator just shows a white screen and the chrome debug screen doesn’t print anything. If I run it without --livereload, it works fine, though I won’t be able to debug it. It also works fine (with --livereload) if testing on a device via USB.

Any idea why, or how I can get it to work on the emulator?
