Have you guys looked at this? https://stackoverflow.com/questions/38418998/react-native-fetch-network-request-failed

[clearloop]

if someone try to use emulator fetching "http://localhost/" or http://127.0.0.1/,
change them to '10.0.2.2'

you can try your ip instead of localhost

[JosePaulo95]

Dont get your ip from a website like findmyip.com go to the cmd and ipconfig

I had the same error using http://localhost:8000 as my development server.

I think on react native 0.52.x it worked fine, but after upgrading to 0.54.x it caused the network request failed error.

As mentioned in https://github.com/facebook/react-native/issues/16081#issuecomment-332762429 and https://github.com/facebook/react-native/issues/16081#issuecomment-352639342, replacing localhost with my actual IP (not 127.0.0.1) didn't cause the error anymore.
