Inquiry to solution

Hi,

I see a solution was reached here but no indication of what it was has been posted. Do you mind clarifying the error you found to make this post more valuable to others facing the same issue?

I've been out of the office for a few days. I'm hoping to get back to this today. I will let you know. Thanks


I found my error and things are working now. Thank you for your help!

There's no obvious issue in the logs.
So the only explanation is that your username and/or password does not match.
Are there any special characters in your username or password?

One thing I did check was that the Fingerprint values agreed and they do. I appreciate your time looking into this.

Thanks!

Re: Issue connecting to SFTP server, command exit status 0

There's no obvious error in the code. Can you post WinSCP_SessionLog_* as well as session log from the GUI?
JMPearson

Issue connecting to SFTP server, command exit status 0

I've been experimenting with the WinSCP .NET DLL. I've had success using it to connect to an FTP site, but not to an SFTP site. When I try to connect to the SFTP site I get the following message:

Connection has been unexpectedly closed. Server sent command exit status 0

This is my code: 

Private Sub ConnectToSite()



    Dim strDebugLogFileName As String = ""

    Dim strSessionLogName As String = ""



    Try

        If oSession Is Nothing Then

            oSessionOptions = New SessionOptions

            oSession = New Session



            If Me.rbFTP.Checked = True Then

                With oSessionOptions

                    .Protocol = Protocol.Ftp

                    .HostName = "XXX.XXXXX.XX.XX"

                    .UserName = "XXXXXXXXXXX"

                    .Password = My.Settings.FTPaccess                        

                End With

            Else

                With oSessionOptions

                    .Protocol = Protocol.Sftp

                    .HostName = "XXXXXXXX.XXXX.XXX.XXX"

                    .UserName = "XXXXXXXXXXXXXXXX"

                    .Password = My.Settings.SFTPaccess                        

                    .SshHostKey = "ssh-xxx xxxx XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX"

                End With

            End If

            strDebugLogFileName = "\WinSCP_DebugLog_" & Format(Now, "yyyyMMdd") & "_" & Format(Now, "HHmmss") & ".txt"

            strSessionLogName = "\WinSCP_SessionLog_" & Format(Now, "yyyyMMdd") & "_" & Format(Now, "HHmmss") & ".txt"



            Using oSession

                oSession.DebugLogPath = Application.StartupPath & strDebugLogFileName                    

                oSession.SessionLogPath = Application.StartupPath & strSessionLogName                    

                oSession.Open(oSessionOptions)

            End Using



            Me.lblConnected.Visible = True

        End If

    Catch ex As Exception

        MessageBox.Show(ex.Message & vbCrLf & vbCrLf & ex.StackTrace, Me.Text, MessageBoxButtons.OK, MessageBoxIcon.Error)

    End Try



End Sub


When I look at the Debug file I'm creating it says that Authentication failed. My first reaction is that my password might be incorrect. I've double-checked it several times and it should be correct. I am able to connect to the SFTP site using the WinSCP GUI and FileZilla with no issues. Is there something in my code that I'm overlooking and not setting right?

Thanks!
