我的几个网站突然出现了这个错误,我不确定问题是什么。这些网站已经运行 2 年多了,这是我第一次看到这个错误。

“连接尝试失败,因为连接方在一段时间后没有正确响应,或者连接失败,因为连接的主机没有响应 XX.XX.XXX.XXX:80”

堆栈跟踪如下。

[SocketException (0x274c): A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond XX.XX.XXX.XXX:80]
   System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) +239

跟踪告诉我它与套接字有关,但没有套接字编程。

您没有直接使用套接字,而是发出了一个在内部使用套接字的远程 Web 请求,因为这是在大多数平台上进行网络连接的方式。由于存在网络问题,您最终会看到套接字异常。

该错误转换为“我无法打开与远程服务器的连接。请检查地址,确保它正在侦听适当的端口并确保我们没有防火墙。”
