FLTFirebaseMessaging: An error occurred while calling method Messaging#getToken

Question

we are enabling push notification with firebase in our Flutter app, but it's returning this error on my real device when I want to sign in. I don't know where is the error, and it's happening only with IOS. Android has no problems. I have followed the official documentation, too. Xcode: 15.2, Flutter: 3.19.5

here is the error message:

FLTFirebaseMessaging: An error occurred while calling method Messaging#getToken, errorOrNil => {
    NSErrorFailingURLKey = "https://device-provisioning.googleapis.com/checkin";
    NSErrorFailingURLStringKey = "https://device-provisioning.googleapis.com/checkin";
    NSLocalizedDescription = "The request timed out.";
    "_NSURLErrorFailingURLSessionTaskErrorKey" = "LocalDataTask <9BEF5303-AEAA-4005-9A7D-D8307A35D3D5>.<1>";
    "_NSURLErrorRelatedURLSessionTaskErrorKey" =     (
        "LocalDataTask <9BEF5303-AEAA-4005-9A7D-D8307A35D3D5>.<1>"
    );
    "_kCFStreamErrorCodeKey" = "-2103";
    "_kCFStreamErrorDomainKey" = 4;
}

here is how I initialize the initFirebase code for token:

Future<void> initFirebase() async {
  String? fcmToken;
  await Firebase.initializeApp(
      options: FirebaseOptions(
          apiKey: Platform.isAndroid
              ? "AIzaSyBuRrD9IUg721orGNJzUPw_6jBqzW0qbgcw"
              : "AIzaSyDpy26KbxDkillvYaBlX_lqvmXC1XOQSpA",
          appId: Platform.isAndroid
              ? "1:199061089561:android:bc4deb3u87dd11a1af0d90"
              : '1:199061089961:ios:09e1ew1avp141a86af0d90',
          messagingSenderId: "199061680561",
          iosBundleId: "com.flutter.truck",
          storageBucket: "truck-19121.appspot.com",
          projectId: "truck-19121"));
  if (Platform.isAndroid) {
    fcmToken = await FirebaseMessaging.instance.getToken();
  } else if (Platform.isIOS) {
    fcmToken = await FirebaseMessaging.instance.getAPNSToken();
    if (fcmToken != null) {
      await Future<void>.delayed(
        const Duration(
          seconds: 5,
        ),
      );
      fcmToken = await FirebaseMessaging.instance.getAPNSToken();
    }
  }
  printColored("FCM USER TOKEN: $fcmToken", PrintedColors.red);

  // FOREGROUND MESSAGE HANDLING.
  FirebaseMessaging.onMessage.listen((RemoteMessage message) {
    debugPrint(
        "NOTIFICATION FOREGROUND MODE: ${message.notification!.title} in foreground");
    debugPrint("NOTIFICATION DATA: ${message.data} in terminated");
    LocalNotificationService.localNotificationService
        .showRemoteNotification(message);
  });

  // BACkGROUND MESSAGE HANDLING
  FirebaseMessaging.onBackgroundMessage(_firebaseMessagingBackgroundHandler);

  // FROM TERMINATED MODE

  handleMessage(RemoteMessage message) {
    debugPrint(
        "NOTIFICATION FROM TERMINATED MODE: ${message.notification!.title} in terminated");
    debugPrint("NOTIFICATION DATA: ${message.data} in terminated");
    LocalNotificationService.localNotificationService
        .showRemoteNotification(message);
  }

  RemoteMessage? remoteMessage =
      await FirebaseMessaging.instance.getInitialMessage();

  if (remoteMessage != null) {
    handleMessage(remoteMessage);
  }

  FirebaseMessaging.onMessageOpenedApp.listen(handleMessage);
}

Future<void> _firebaseMessagingBackgroundHandler(RemoteMessage message) async {
  await Firebase.initializeApp();
  LocalNotificationService.localNotificationService
      .showRemoteNotification(message);
  debugPrint(
      "NOTIFICATION BACKGROUND MODE: ${message.notification!.title} in background");
  debugPrint("NOTIFICATION DATA: ${message.data} in terminated");
}

the solution was with Firebase installation sdk in my Xcode and integrate with the console
