Detailed Problem Description
I'm trying to implement email/password authentication using Firebase Auth in a React Native app with Expo SDK 53 (Hermes enabled). Everything is working fine on the Android emulator, but on the iOS simulator I consistently get the following error when calling createUserWithEmailAndPassword:
vbnet
Firebase: Error (auth/network-request-failed)
Here’s additional logging from the console:
📧 Email: test@example.com
🔐 Password: ********
🧪 Type check: string string
❌ Firebase ping failed: [TypeError: Network request failed]
I’ve confirmed:
The email and password are valid.
Firebase is initialized correctly using firebase/auth/react-native.
I’m using getReactNativePersistence(AsyncStorage) in initializeAuth.
My .env file has the correct Firebase config.
I am testing this on a Mac with the iOS simulator using a physical network connection (not offline).
The Firebase project has email/password login enabled.
Authorized domains are set up in Firebase (localhost, 127.0.0.1, etc.)
Despite all of this, iOS throws a network error every time I try to sign up or sign in a user.
This issue seems specific to the iOS simulator and doesn’t appear on Android.
Steps and code to reproduce issue
// firebase.js
import { initializeApp } from 'firebase/app';
import { getAuth, initializeAuth, getReactNativePersistence } from 'firebase/auth/react-native';
import AsyncStorage from '@react-native-async-storage/async-storage';
const firebaseConfig = {
apiKey: 'MY_API_KEY',
authDomain: 'MY_PROJECT.firebaseapp.com',
projectId: 'MY_PROJECT',
storageBucket: 'MY_PROJECT.appspot.com',
messagingSenderId: '...',
appId: '...'
};
const app = initializeApp(firebaseConfig);
const auth = initializeAuth(app, {
persistence: getReactNativePersistence(AsyncStorage),
});
export { auth };
import { createUserWithEmailAndPassword } from 'firebase/auth';
import { auth } from './firebase';
await createUserWithEmailAndPassword(auth, email, password);
Firebase: Error (auth/network-request-failed)
