.NET assembly automation SSH server error

I'm getting the "incoming packet was garbled on decryption" error when using the .net assembly to connect to the server...
i searched the forums and faqs, but only found info using the gui...
i even set the defaults on the gui based on what i read...
is there a way to programatically set up something to connect?

here's the log output:

here's the code:
SessionOptions sftpOpts = null;

try
{
sftpOpts = new SessionOptions();
sftpOpts.HostName = f_server;
sftpOpts.UserName = f_user;
sftpOpts.Password = f_pass;
sftpOpts.Protocol = Protocol.Sftp;
//sftpOpts.FtpMode = FtpMode.Active;
sftpOpts.SshHostKey = "ssh-dss 1024 90:a8:5e:52:07:48:7e:e8:7f:93:c2:5f:b0:13:61:07";


_ftp = new Session();
_ftp.Open(sftpOpts);

thanks in advance...

Were you able to connect with the GUI?

No...i couldn't connect w/ the gui either...
i'm connecting to a server using moveIT...
they say that the command line winscp is supported...

OK, are you able to connect with any other SSH client?

Also see:
https://winscp.net/eng/docs/message_incoming_packet_was_garbled_on_decryption

i am able to connect with moveITFreely, so yes...
also, regarding the link, i was unable to connect w/ the gui with that option set up...
i was curious how i could set that in the .net assembly?
i would like to use this code set...it is very well built..
thank you for the good work...

You would set it using SessionOptions.AddRawSettings
https://winscp.net/eng/docs/library_sessionoptions_addrawsettings

Anyway, as it wouldn't help... Any chance of getting a test account on your server?
