这是我在讨论论坛上提出的一个老问题。不幸的是，这是一个问题，它又回来了，我又一次需要一个解决方案！

精华是：

将应用程序部署到Azure生产环境和UAT环境时，我遇到了以下问题。在本地运行此应用程序不会造成任何问题。该应用程序尝试连接到列表directorys或在短时间内将文件下载到流中。但是，在第一次尝试连接后，测试用例中会抛出此异常。但是，还应该注意的是，这并不总是会发生，因此客户端连接成功。

var connInfo = new PasswordConnectionInfo(this.host, this.port, this.username, this.password);
        using (this.client = new SftpClient(connInfo))
        {
            client.ErrorOccurred += new EventHandler<Renci.SshNet.Common.ExceptionEventArgs>(client_ErrorOccurred);

            this.client.Connect();

            var response = new MemoryStream();
            this.client.DownloadFile(this.intraDayFilePath, response);


            this.client.Disconnect();
        }

例外：

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 xxx.xxx.xxx.xxx:22

在Azure上运行的SFTP代码偶尔会出现与服务器的连接问题
