# 代理无法使用
**问题：** 我购买了数据中心代理，但它们不起作用！\
**答案：** 更新端点服务器需要一些时间，从购买之日起最多需要 3 分钟。\
\
**问题：** 3分多钟过去了，代理仍然无法工作！\
**答案：** 使用我们的[代理测试器](https://proxyshard.com/proxy-tester) 检查代理或通过命令行（终端）检查您这边的连接。
通过curl和Proxy Tester检查的详细说明：[如何检查代理是否工作](/cn/wen-da/faq/how-to-check-proxy.md)
***
**如果检查成功：**
如果您仍然无法通过插件、浏览器或程序进行连接，请检查输入的数据是否正确以及软件是否正常运行。 **SOCKS 和 HTTP 代理连接协议经常混淆。** 我们不提供与 **ProxyShard** 项目无关的软件或硬件的支持，除非该问题是由我们的问题引起的侧面.
**如果检查失败：**
再次重新检查数据。如果确实正确，请尝试通过 VPN 检查以排除 ISP 的阻止。无论如何，请联系**我们的技术支持**；如果问题在我们这边，我们将尽力快速识别并解决问题。
**如果它有效，但不适合我：**\
如果代理之前可以工作但突然停止，在通过我们的[代理测试器](https://proxyshard.com/proxy-tester)、VPN 或其他资源检查确认代理仍然存在时，**您的 ISP 可能正在阻止连接**。 **尝试使用 SOCKS 端口或联系我们的技术支持。**
