C＃xamarin android无法连接到任何指定的MySQL主机

Question

I am trying to make a simple app that will connect to a database and get some info. I have implented the plugin that allows xamarin app to connect remote mariaDB/MySQL to components. I am using the code below.

    public void GetAccountCountFromMySQL()
    {
        try
        {

            string sql = " SELECT * FROM Kategorier";
            MySqlConnection con = new MySqlConnection("Persist Security Info=False; Server=192.210.241.161; Port=3306; Database=xxxxx; Uid=xxxxx; Pwd=xxxxx;");
            MySqlCommand cmd = new MySqlCommand(sql, con);

            con.Open();

            MySqlDataReader reader = cmd.ExecuteReader();

            while (reader.Read())
            {
                Console.WriteLine(reader.GetString("Sko"));
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
    }

I have tried many types of connection strings, also I buileded a simple C# application that connects to the very same database with no problems.

实际问题是来自MySql的错误“无法解析主机名”讨论后决定不使用此插件，因为它不安全但创建了一个与MySql DB通信的Web服务并从Android应用程序中使用它。
