React Native Fetch Network Request Failed on Android

React Native fetch() Network Request Failed

The problem here is that iOS does not allow HTTP requests by default, only HTTPS. If you want to enable HTTP requests add this to your info.plist:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

TypeError: Network request failed (React Native) Android fetch fails to work with local backend

127.0.0.1 represents the emulator's localhost address. If you want to hit your machine's localhost you'll have to replace it with 10.0.2.2.

See Android docs for more information on why this is the case.

Network request failed - fetching from localhost ReactNative

I solved the issue. The error was not because of react native but from my asp.net core API. Basically, I just needed to change my code in the launchsettings.js in the Properties folder from "applicationUrl": "https://localhost:5001;http://localhost:5000" to "applicationUrl": "http://localhost:5000"

This solved the issue and fetching from localhost in react native worked without any further issues. This stack question helped me figure this out: How to fix network error in react-native when access localhost api
