Please post also a session log file from the .NET (using Session.SessionLogPath). Thanks.

I am trying to connect to a server on a VPN connection with the following code just to see if it will open the connection (using the real hostname, username, password, hostkey, etc on my end):

Try
Dim sessionOptions As New SessionOptions
With sessionOptions
.Protocol = Protocol.Sftp
.HostName = "serverName"
.UserName = "userName"
.Password = "password"
.SshHostKey = "ssh-rsa 2048 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx"
End With

Using session As Session = New Session
session.Open(sessionOptions)
End Using

Catch ex As Exception
Console.WriteLine("Error: {0},", ex)
End Try




I get the following log file:

I can connect to the server just fine through the GUI, but I do get a security banner and another prompt afterwards I have to click ok for. I tried the command line option to see if it was something I was doing with the .NET assembly. Script file for command line test.txt:

option batch on
option confirm off
open sftp://user:password@server.com
close
exit

winscp.exe /console /script=test.txt

This generated the following log file:

I did as much looking around as I could before posting this and found an old bug that seems to have this behavior. https://winscp.net/tracker/388

Is this the problem I am having or am I doing something else wrong?

Thanks,
