It looks like you are using an older version of React Native. Please update to the latest release, v0.60 and verify if the issue still exists.

Details

The "Resolution: Old Version" label will be removed automatically once you edit your original post with the results of running `react-native info` on a project using the latest release.

I'm leaning towards closing this for two reasons: 1) insufficient repro steps (apparently it stopped working without any changes to the product code), and 2) you already worked around this by using the localhost ip address directly.
