Android Question FTP File upload not working

[gmachacek]

Hallo world,
i need to upload a file via FTP to MS Server 2025 with IIS 10.
I am using FTP with explicit SSL.
Logon is working and LIST also but uploading a file gives error 550 Access denied.

The user for sure has all rights, Filezilla and SCP is working fine with same credentials.

Here are the Filezilla settings:

This is my code using the NET library V1.83 with B4a V13.40

public Sub sendFtp
    Try
       
        If File.Exists( File.DirDefaultExternal, "tempPic.jpg") Then
       
            Dim ftp As FTP
            ftp.Initialize("ftp", "ftp.baubuch.at", 21, "xxxuserxxx", "xxxpwdxxx")

            ftp.PassiveMode = True
            ftp.UseSSL = False
            ftp.UseSSLExplicit = True
            ftp.TimeoutMs = 6000
           
            Wait for (ftp.List("/")) FTP_ListCompleted (serverPath As String, Success As Boolean, Folders() As FTPEntry, Files() As FTPEntry)
            If Success = False Then
                Log(LastException)
            Else
                For i = 0 To Folders.Length - 1
                    Log(Folders(i).Name)
                Next
                For i = 0 To Files.Length - 1
                    Log(Files(i).Name & ", " & Files(i).Size & ", " & DateTime.Date(Files(i).Timestamp))
                Next
                Log("FTP Success")
            End If
           
            Wait For(ftp.UploadFile(File.DirDefaultExternal, "tempPic.jpg", False, "/")) FTP_UploadCompleted(serverPath As String, Success As Boolean)
            If Success Then
                ftp.Close
                Log("Ftp file upload successfully!")
            Else
                ftp.Close
                Log(LastException)
                Return
            End If

        End If

    Catch
        Log("sendFTP: " & LastException)
    End Try
End Sub

Hope somebody has an idea, maybe i did understand something wrong, or i just do not see my bug after hours.

Thx in advance regards
Georg

Code with File.DirDefaultExternal = broken code. Use File.DirInternal or RuntimePermission.GetSafeDirDefaultExternal.

The ServerFilePath parameter (last one) is the full path to the remote file. It cannot be '/'.

Try it with:

ftp.UploadFile(File.DirDefaultExternal, "tempPic.jpg", False, "tempPic.jpg")

This will upload the file to the current folder.

Hallo Erel,
the RuntimePermission i give on other position in the code.
DirDefaultExternal i just use during programming, because i think its easier to open and find files on the device.

The problem was realy the path, my fault i should better read description !

Thank you it works perfect!
