Couldnt connect() with server - Renci.SshNet.Common.SshConnectionException

Hi there,

When I try to connect with the server then I am getting the below error.

please help.

Renci.SshNet.Common.SshConnectionException: An existing connection was forcibly closed by the remote host ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host
at System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags)

Start at Renci.SshNet.Session.Connect() and follow the reported stack through ReceiveMessage() and SocketAbstraction.Read(). Reproduce the connection using the server and configuration from FtpEngine.ftp.Upload.UploadFilestoSFTPUsingSSH, which are not included here. Done means identifying the remote-close cause and documenting or testing a confirmed fix.
