I have SFTP server which is able to connect via (Bitvise SSH client) with the help of Obfuscation Password. But, unable to connect the same via c# code.

Here is my code:

winSCPSrc.SessionOptions sessionOptionss = new winSCPSrc.SessionOptions();
sessionOptionss.Protocol = winSCPSrc.Protocol.Sftp;
sessionOptionss.PortNumber = Port;
sessionOptionss.HostName = Host;
sessionOptionss.UserName = Username;
if (!string.IsNullOrEmpty(Password))
{
    sessionOptionss.Password = Password;
}
//sessionOptionss.GiveUpSecurityAndAcceptAnySshHostKey = true;
sessionOptionss.SshHostKeyFingerprint = fingerPrint;

using (winSCPSrc.Session session = new winSCPSrc.Session())
{
    State.KPILog.Info(" SFTP Connection trying to Open ");
    session.AddRawConfiguration("DefaultConfiguration", "false");
    // Connect
    session.Open(sessionOptionss);
    State.KPILog.Info("SFTP Connection Open ");
    // ...
}

I'm getting "Server unexpectedly closed network connection" error while session.Open(sessionOptionss).

Please let me know there is any other libraries available other than winscp to connect SFTP.

What I have tried:

• Able to connect and download files via Bitvise SSH client but unable to implement it in C# code.

• Our IT provider has given some "Obfuscation Password" for connecting via Bitvise ssh client. I have no idea how it works in C# code.
