title: Firebase "no auth token for request" Error
body: <p>I'm trying to download a file from Firebase. I've done all the requirements to set up the cloud Storage from Firebase and made my cloud storage open :</p>
  
  <pre><code>rules_version = '2';
  service firebase.storage {
    match /b/{bucket}/o {
      match /{allPaths=**} {
        allow read, write;
      }
    }
  }
  </code></pre>
  
  <p>I have a single <code>materialButton</code> that, when clicked, should download the file from the cloud storage and store it in the Download Directory. Here's my code</p>
  
  <pre><code>public class MainActivity extends AppCompatActivity {
  
  
      MaterialButton mconvertButton;
      FirebaseStorage mfirebaseStorage;
      StorageReference mstorageReference;
      StorageReference ref;
  
      @Override
      protected void onCreate(Bundle savedInstanceState) {
  
          mconvertButton = findViewById(R.id.convertButton);
          mconvertButton.setOnClickListener(new View.OnClickListener() {
              @Override
              public void onClick(View v) {
                  download();
              }
          });
  
      }
      public void download(){
          mstorageReference = FirebaseStorage.getInstance().getReference();
          ref = mstorageReference.child("_HDbN_ugHkQ.wav");
          ref.getDownloadUrl().addOnSuccessListener(new OnSuccessListener&lt;Uri&gt;() {
              @Override
              public void onSuccess(Uri uri) {
                  String url = uri.toString();
                  downloadFiles(MainActivity.this, "_HDbN_ugHkQ",
                          ".wav", DIRECTORY_DOWNLOADS, url);
              }
          }).addOnFailureListener(new OnFailureListener() {
              @Override
              public void onFailure(@NonNull Exception e) {
                  e.printStackTrace();
              }
          });
      }
  
      public void downloadFiles(Context context, String fileName, String fileExtension, String destinationDirectory, String url){
          DownloadManager downloadManager = (DownloadManager) context.
                  getSystemService(Context.DOWNLOAD_SERVICE);
          Uri uri = Uri.parse(url);
          DownloadManager.Request request = new DownloadManager.Request(uri);
  
          request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
          request.setDestinationInExternalFilesDir(context, destinationDirectory, fileName + fileExtension);
  
      }
  </code></pre>
  
  <p>However, everytime I click the button, I get back :</p>
  
  <pre><code>W/StorageUtil: no auth token for request
  W/NetworkRequest: no auth token for request
  </code></pre>
  
  <p>I've tried to clean my app data, I've tried to uninstall and reinstall my app. I checked multiple time that my app was still connected to firebase but the problem remains. 
  Do you have any ideas on how to solve this ?</p>
