EvtID:10060:Cannot connect to....A network-related or instance-specific error occurred while establishing a connection to SQL Server
我正在尝试通过 SQL Server Management Studio (SSMS) 2017/18 从我的本地计算机连接 Azure Cloud Sql Database。在服务器防火墙规则中添加了客户端 IP，但未连接并引发如下错误。

还执行了以下操作：
-网络重置
-IPV4和IPV6 DNS服务器地址更新。
-SQL 服务器配置管理器 IPV4 TCP 启用禁用
-SQL 服务器服务停止，启动。
-系统 windows 10 64 位最新。
-网络驱动卸载安装
-Telnet

-C# sql 客户：
我尝试过使用 c# Sql 客户端的示例控制台应用程序，但遇到了同样的问题。
不明白是什么问题？非常感谢帮助。
你能给我建议解决方案吗？
提前致谢。
我的系统防火墙入站设置中没有 TCP 端口 1433 有问题。
所以做了以下步骤
- 为端口 1433 启用协议
-创建防火墙例外
-并申请到数据库引擎实例服务
有关更多详细信息，请参考 link here。
按照相同的参考 link 问题解决了。
