It looks like you are using an older version of React Native. Please update to the latest release, v0.57 and verify if the issue still exists.

The "⏪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.

Maybe same as #22375 if your URLs are not HTTPS.
