Why I'm getting network unavailable, sleeping when I try to post some data to a firebase database?

Question

I'm creating an app and at every Post Request I make to the Firebase Database it throws me this error

W/ExponenentialBackoff: network unavailable, sleeping.
W/NetworkRequest: error sending network request POST https://firebasestorage.googleapis.com/v0/b/*********/o

I added my SHA-1 KEY to the Firebase console, but still the same. Funny fact that yesterday when I made the project it was working. I google the error and the solutions were to add 'firebase auth ' in the build.gradle, but I do have already those implementations:

   implementation 'com.google.firebase:firebase-analytics:17.2.0'
    implementation 'com.google.firebase:firebase-auth:19.1.0'
    implementation 'com.google.firebase:firebase-database:19.1.0'
    implementation 'com.google.firebase:firebase-storage:19.1.0'

Can you please tell me how to solve this or at least give me some information to understand what I have to do to handle this? Thank you!

Database Rules

rules_version = '2';

service cloud.firestore {

  match /databases/{database}/documents {

    match /{document=**} {

      allow read, write;

    }

  }

}

Storage Rules

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

Answer 1

It worked for me after uninstalling the app and reinstalling it again I hope you have added the required permissions.
