Web服务突然停止响应/工作 [英] Web Services suddenly stopped responding / working
问题描述
如果这不是正确的论坛，我道歉。但我甚至不确定从哪里开始。我们有2个Web服务 - 一个是从服务器检索文档的"自定义"Web服务，另一个是从FAND服务器检索文档的Web服务。昨天早上'突然'他们停止了工作。我们遇到的错误如下：
*** System.Net.WebException：无法从传输连接读取数据：远程主机强制关闭现有连接。 ---> System.IO.IOException：无法从传输连接读取数据：远程主机强制关闭现有连接。 ---> System.Net.Sockets.SocketException：远程主机强行关闭现有连接

任何人都可以帮忙吗？我知道服务停止时系统上没有任何改变。我们已尝试停止并重新启动服务，并停止并重新启动整个Web服务器。仍然没有工作。
也许网络人员安装了新的代理服务器或防火墙？这可能。
I apologize if this isn't the correct forum . .but I'm not really sure even where to start. We have 2 web services - one a 'custom' web service that retrieves documents from a server and another one that retrieves documents from a FAND server. 'Suddenly' yesterday morning they stopped working. We are getting errors such as:
*** System.Net.WebException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

Can anyone help please? We had not changed anything on the system that I know of when the services stopped. We have tried stopping and restarting the services and stopping and restarting the entire web server. Still not working.
Perhaps the network guys installed a new proxy server or firewall? Is that possible.
