Using Expo, this only works 2/3 of the time, the other 1/3 I get this error. It sometimes goes away by just restarting, reloading or other ‘magic’ stuff, but I’d prefer to figure out how to get it working 3/3 times. Any steps I can take?

@marcusegues Have you reversed your ports using the ADB? (via running adb reverse tcp:8000 tcp:8000)

That’s usually the most common reason for socket hung up - keep in mind that if you disconnect the device from your computer, the port doesn’t remain reversed; You have to (re-)run that ADB command every time you connect your device.
