Connection Attempt failed when trying to connect to MFT

Hi Team,

We are receiving two errors at irregular intervals from SFTP Baseclient.connect method while connecting to MFT server:

"System.Net.Sockets.SocketException: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"

":Renci.SshNet.Common.SshConnectionException:InnerException:System.Net.Sockets.SocketException (0x80004005): An existing connection was forcibly closed by the remote host
at System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags)
at Renci.SshNet.Abstractions.SocketAbstraction.Read(Socket socket, Byte[] buffer, Int32 offset, Int32 size, TimeSpan timeout)
at Renci.SshNet.Session.TrySocketRead(Byte[] buffer, Int32 offset, Int32 length)
at Renci.SshNet.Session.ReceiveMessage()
at Renci.SshNet.Session.MessageListener():Message:An existing connection was forcibly closed by the remote host"

We have increased the Connection Timeout to 50 secs as well. using stable version: 2016.1.0

Please help to resolve the issues.

Thanks,
Haritha

Start at the SFTP Baseclient.connect path and trace the reported SocketException and SshConnectionException stack frames through the connection flow. Reproduce the intermittent failure against the MFT server with the 50-second timeout, then document a reliable cause and verify that the connection no longer fails unexpectedly.
