Answer 1

usually this is a network connection problem

Answer 2

App Check Attestation Providers: For IOS: DeviceCheck or App Attest & For Android: Play Integrity or SafetyNet

Use Anyone of these you like, I personally use SafetyNet for my android apps.

1. Add this inside apps/build.gradle:

dependencies { implementation 'com.google.firebase:firebase-appcheck-safetynet:16.0.0' }

2. Then Initialize App Check Add this:

FirebaseApp.initializeApp(/context=/ this); FirebaseAppCheck firebaseAppCheck = FirebaseAppCheck.getInstance(); firebaseAppCheck.installAppCheckProviderFactory( SafetyNetAppCheckProviderFactory.getInstance());

I hope it fix your error. for more you can follow official doc: [https://firebase.google.com/docs/app-check/android/safetynet-provider].

Another Temporary fix... for TP & Practice Apps

Simply Remove If Condition from your firebase storage/db/auth rules

rules_version = '2'; service firebase.storage { match /b/{bucket}/o { match /{allPaths=**} { allow read, write: if false; } } }
