Unity Editor wont connect to firebase auth - firebase

Question

I'm here to make a game with anonymous login with firebase auth, and a database with firebase real-time database, everything works smoothly except for firebase auth. The problem is I don't know why? the unity won't connect to firebase auth.
Installation
I already install the package like always database and auth
also for the firebase is like this
Script
here my login script :
//Firebase variables
[Header("Firebase")]
public DependencyStatus dependencyStatus;
public FirebaseAuth auth;
public FirebaseUser User;
public DatabaseReference DBreference;
public static FirebaseManager instance;
void Awake()
{
if (instance != null)
{
Destroy(gameObject);
}
else
{
DontDestroyOnLoad(gameObject);
instance = this;
}
FirebaseApp.CheckAndFixDependenciesAsync().ContinueWithOnMainThread(task =>
{
dependencyStatus = task.Result;
if (dependencyStatus == DependencyStatus.Available)
{
InitializeFirebase();
}
else
{
Debug.LogError(
"Could not resolve all Firebase dependencies: " + dependency status);
}
});
}
public void InitializeFirebase()
{
auth = FirebaseAuth.DefaultInstance;
DBreference = FirebaseDatabase.DefaultInstance.RootReference;
auth.StateChanged += AuthStateChanged;
AuthStateChanged(this, null);
}
void AuthStateChanged(object sender, System.EventArgs eventArgs)
{
//This checks if the user (your local user) is the same as the one from the auth
if (auth.CurrentUser != User)
{
bool signedIn = User != auth.CurrentUser && auth.CurrentUser != null;
User = auth.CurrentUser;
if (signedIn)
{
Debug.Log("Signed in " + User.UserId + " " + User.DisplayName);
}
else
{
StartCoroutine(SignAnonymously());
}
}
}
//it does not directly log the user out but invalidates the auth
void OnDestroy()
{
auth.StateChanged -= AuthStateChanged;
auth = null;
}
public IEnumerator SignAnonymously()
{
var loginTask = auth.SignInAnonymouslyAsync();
yield return new WaitUntil(predicate: () => loginTask.IsCompleted);
if (loginTask.Exception != null)
{
//If there are errors handle them
Debug.LogWarning(message: $"Failed to register task with {loginTask.Exception}");
}
else
{
User = loginTask.Result;
Debug.LogFormat("User signed in successfully: {0} ({1})", User.DisplayName, User.UserId);
}
}
What I've tried
Check the google-service.json ( already same or updated )
already implement this https://firebase.googleblog.com/2020/08/firebase-compatibility-with-unity-20201.html due to a compatibility issue.
already changed continuewith to ContinueWithOnMainThread(task..
note: I'm using unity ver 2020.3.1f1 LTS
am I doing it wrong?

Try to replace your Coroutine method SignAnonymously with this async method:
public async void SignAnonymously()
{
await auth.SignInAnonymouslyAsync().ContinueWith(task => {
if (task.IsCanceled) {
Debug.LogError("SignInAnonymouslyAsync was canceled.");
return;
}
if (task.IsFaulted) {
Debug.LogError("SignInAnonymouslyAsync encountered an error: " + task.Exception);
return;
}
Firebase.Auth.FirebaseUser newUser = task.Result;
Debug.LogFormat("User signed in successfully: {0} ({1})",
newUser.DisplayName, newUser.UserId);
});
}
I think that the problem could be the lacking of ContinueWithat the end of your SignInAnonymouslyAsync, maybe you can use it on your Coroutine but I've never done it that way, tell me if it works ^^
