Session.GetFiles loops and does not return my hand

Here my code: 
Dim Serveur As String
Dim OriIP As String
'***
ProgressBar.Value = 0
ProgressBar.Maximum = 0
'***
If RadioPresles.Checked Then
    Serveur = "PRESLES"
ElseIf RadioLesArcs.Checked Then
    Serveur = "LESARCS"
Else
    Serveur = "LINSELLES"
End If
'***
Call Affichage("Fichier du " & MyDateDonnees & " en cours de téléchargement à partir du serveur " & Serveur, True, False)
'***
If RadioPresles.Checked Then
    OriUri = UriPresles
    OriIP = UriPreslesIn
Else
    If RadioLesArcs.Checked Then
        OriUri = UriLesArcs
        OriIP = UriLesArcsIn
    Else
        OriUri = UriLinselles
        OriIP = UriLinsellesIn
    End If
End If
Interne:
Try
    ' Setup session options
    Dim sessionOptions As New SessionOptions
    With sessionOptions
        .Protocol = Protocol.Ftp
        .FtpMode = FtpMode.Passive
        .PortNumber = 50000
        .HostName = OriUri
        .UserName = userName
        .Password = password
    End With
    Using session As New Session
        session.Open(sessionOptions)
        Dim transferOptions As New TransferOptions
        transferOptions.TransferMode = TransferMode.Binary
        Dim transferResult As TransferOperationResult
        transferResult = session.GetFiles(MyFile, ".\", False, transferOptions)
        transferResult.Check()
    End Using

    Call Affichage("Erreur de chargement, veuillez réessayer...", False, False)

The session.GetFiles loops and does not return my hand:

Re: Session.GetFiles loops and does not return my hand

Please attach a full session log file showing the problem (using the latest version of WinSCP).

To generate the session log file, set Session.SessionLogPath. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.

Probably due to a DNS resolution problem behind a NAT server ... I'm not sure ...

So does WinSCP GUI work (on the same local machine)? Can you see the directory contents? Or any other FTP client (on the same local machine)?
