针对read_timeout的Firebase消息取消注册通知失败

我试图从一台设备向另一台设备发送通知，让用户知道有一条等待他的消息。

当我试图捕获并处理 RemoteMessage 时，控制台会打印出这样的内容。它发生在 iOS 物理设备上。

该功能以前运行良好，但现在无法通过设备、客户端向其他用户发送通知。

功能概述：

  static Future<void> sendNotificationToOtherUser(
      String title, String body, String token) async {
    final headers = {
      'content-type': 'application/json',
      'Authorization':
          'key={I hide KEY but I assure you there is nothing wrong with key}'
    };
    List<String> list = List();
// token is not null
    list.add(token);
    final postUrl = 'https://fcm.googleapis.com/fcm/send';
    final data = {
      "registration_ids": list,
      "notification": {
        "title": '$title',
        "body": '$body',
      },
    };

    final response = await http.post(Uri.parse(postUrl),
        body: json.encode(data),
        encoding: Encoding.getByName('utf-8'),
        headers: headers);

    if (response.statusCode == 200) {
      // it prints 200 so works perfectly
      print(response.body);
      print('test ok push CFM');
      return true;
    } else {
      print(response.body);
      print(' CFM error');
      // on failure do sth
      return false;
    }
  }

似乎一切正常，但其他设备无法捕获通知并由于我在下面放置的错误而显示它。错误：
