[🐛] @react-native-firebase/auth - auth/network-request-failed on Chinese Android phone.

[thanhlongnguyen140499]

-I'm facing an issue when using @react-native-firebase/auth with React Native CLI in a React Native app.

• What I’m trying to do:
  Sign up or log in a user via signInWithEmailAndPassword and createUserWithEmailAndPassword

• What happens:
  On real Android devices, the request fails with the error: auth/network-request-failed.

• Environment:
  "@react-native-firebase/analytics": "19.0.1",
  "@react-native-firebase/app": "19.0.1",
  "@react-native-firebase/auth": "19.0.1",
  "@react-native-firebase/crashlytics": "19.0.1",
  "@react-native-firebase/messaging": "19.0.1",
  "react-native": "0.71.2",

• Device:
  Xiaomi, Oppo.

• What I’ve already tried:
  Installed Cloudflare (1.1.1.1) to change DNS -> it works fine.

• Code example:

  auth()
  .signInWithEmailAndPassword(email, password)
  .then(response => {
  if (!response?.user?.emailVerified) {
  response.user.sendEmailVerification();
  setIsLoading(false);
  return;
  } else {
  handleLoginFirebase();
  }
  })
  .catch(err => {
  setIsLoading(false);
  if (err.code === 'auth/user-not-found') {
  return;
  }
  if (err.code === 'auth/wrong-password') {
  return;
  }
  if (err.code === 'auth/too-many-requests') {
  return;
  }
  if (err.code === 'auth/invalid-email') {
  return;
  }
  if (err.code === 'auth/user-disabled') {
  return;
  }
  if (err.code === 'auth/invalid-credential') {
  return;
  }
  console.log(err);
  });
  };

• Firebase.json
  {
  "react-native": {
  "android_task_executor_maximum_pool_size": 10,
  "android_task_executor_keep_alive_seconds": 3,
  "messaging_android_notification_color": "@color/hotpink",
  "messaging_ios_foreground_presentation_options": [

  ],
  "messaging_ios_auto_register_for_remote_messages": false,
  "messaging_android_notification_channel_id": "high-priority-channel",
  "crashlytics_debug_enabled": true
  }
  }

• Logs:
  [Error: [auth/network-request-failed] A network error (such as timeout, interrupted connection or unreachable host) has occurred.]

Hi there, other vendors like Xiaomi are notorious for being problematic and especially with Firebase likely due to its operating system, often times it is due to the aggressive killing of background processes to claim more battery life: https://dontkillmyapp.com/xiaomi the work around for this if it is to do with that is to try disable battery optimisations. This is unfortunately something we cannot directly address. You can also try going to your app settings physically on your phone and change settings related to battery saver if it gives you the option.
Also make sure that you have internet permissions in your AndroidManifest:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
