C# 无法打开连接

我创建了一个连接到服务器以从数据库中检索数据的系统，但是我得到"MySql.Data中发生了类型为'System.TimeoutException'的未处理异常.dll"...

如果我连接到本地主机，一切都很好......

    string StrCon = string.Format("Server= Cant tell you ; database={0};UID= cant tell you ; password='cant tell you '", "cant tell you");
        MySqlConnection Connection = new MySqlConnection(StrCon);
        while (true)
        {
            //MySqlConnection Connection = null;
            Console.WriteLine("not connected");
            Connection.Open();
            Console.WriteLine("connected");
            string Query = "SELECT * FROM lat_long WHERE ID=1";
            MySqlCommand cmd = new MySqlCommand(Query, Connection);
            MySqlDataReader dr = cmd.ExecuteReader();
