Firebase realtime database is not connecting

Iam trying to use firebase real-time database. I have set rules to true and in my project added all required dependencies and also internet permission. My mobile is very well connected to the wifi.

When I tried to use write the data then it's not working. So I checked the status as per documentation and it's showing dB is not connected to my app.

DatabaseReference connectedRef = FirebaseDatabase.getInstance().getReference(".info/connected");
connectedRef.addValueEventListener(new ValueEventListener() {
    @Override
    public void onDataChange(@NonNull DataSnapshot snapshot) {
        boolean connected = snapshot.getValue(Boolean.class);
        if (connected) {
            Log.d(TAG, "connected");
        } else {
            Log.d(TAG, "not connected");
        }
    }

    @Override
    public void onCancelled(@NonNull DatabaseError error) {
        Log.w(TAG, "Listener was cancelled");
    }
});

Am I doing anything wrong hwre?

Appreciate help.

PD

The issue is solved by recreating database and connecting again to the app. Thank you for the answers.

You should add the Query

DatabaseReference connectedRef = FirebaseDatabase.getInstance().getReference();
Query query = connectedRef.child("info/connected");
query.addValueEventListener(new ValueEventListener() { 
    @Override
    public void onDataChange(@NonNull DataSnapshot snapshot) {
        boolean connected = snapshot.getValue(Boolean.class);
        if (connected) {
        Log.d(TAG, "connected");
        } else {
        Log.d(TAG, "not connected");
        }
    }

    @Override
    public void onCancelled(@NonNull DatabaseError error) {
        Log.w(TAG, "Listener was cancelled");
    }
});
