The remote server returned an error: (530) (Not logged in)

Question

I have changed the credentials etc at the bottom of course for security reasons, but could anyone offer any suggestions as to why this isn't working?

I have used these credentials on FileZilla with no problems.

Code:

Imports System.Net
Imports System.IO

Public Class Form1

Private Sub FtpUploadFile(ByVal filetoupload As String, ByVal ftpuri As String, ByVal ftpusername As String, ByVal ftppassword As String)
    ' Create a web request that will be used to talk with the server and set the request method to upload a file by ftp.
    Dim ftpRequest As FtpWebRequest = CType(WebRequest.Create(ftpuri), FtpWebRequest)

    Try
        ftpRequest.Method = WebRequestMethods.Ftp.UploadFile

        ' Confirm the Network credentials based on the user name and password passed in.
        ftpRequest.Credentials = New NetworkCredential(ftpusername, ftppassword)

        ' Read into a Byte array the contents of the file to be uploaded 
        Dim bytes() As Byte = System.IO.File.ReadAllBytes(filetoupload)

        ' Transfer the byte array contents into the request stream, write and then close when done.
        ftpRequest.ContentLength = bytes.Length
        Using UploadStream As Stream = ftpRequest.GetRequestStream()
            UploadStream.Write(bytes, 0, bytes.Length)
            UploadStream.Close()
        End Using
    Catch ex As Exception
        MessageBox.Show(ex.Message)
        Exit Sub
    End Try

    MessageBox.Show("Process Complete")
End Sub

Private Sub Upload_Click(sender As Object, e As EventArgs) Handles Upload.Click
    FtpUploadFile("D:\Directory\Filename.csv", "ftp://www.****.com/test.csv", "****@*****.com", "*********")
End Sub
End Class

as requested I have tried to use WebClient see below code Try

    Dim up As New WebClient
        up.Credentials = New NetworkCredential("username", "password")
    up.UploadFile("ftp://www.domain.com/test.csv", "D:\test\test.csv")
        MsgBox("Done")
        up.Dispose()

    Catch ex As Exception
        MsgBox(ex.Message)
    End Try
End Sub

the results are the same; The remote server returned an error: (530) (Not logged in)

Looks right at a glance...have you tried using [WebClient](https://msdn.microsoft.com/en-us/library/system.net.webclient(v=vs.110).aspx) instead? — MrGadget, Mar 17 '17 at 12:39
@MrGadget i'll not lie, looked into WebClient and haven't got a clue where to start! any suggestions? — JustAnAverageSQLuser, Mar 17 '17 at 13:12
[WebClient.UploadFile](https://msdn.microsoft.com/en-us/library/36s52zhs(v=vs.110).aspx) has an example. It takes a NetworkCredential the same way FtpWebRequest does. Should be 4 lines of code counting the Dispose. — MrGadget, Mar 17 '17 at 13:26
Thanks @MrGadget. I know it should probably mean something to me, but it doesn't. I'll have to keep studying to try and get more help. Thanks for your time — JustAnAverageSQLuser, Mar 17 '17 at 13:49
Hi @MrGadget I have tried the WebClient.uploadFile and the same error is returned. — JustAnAverageSQLuser, Mar 17 '17 at 14:35
Show us [log file](http://stackoverflow.com/q/9664650/850848). — Martin Prikryl, Mar 17 '17 at 14:37
Though it's quite likely that your credentials are simply wrong. Can you login using the same credentials using a standalone FTP client (e.g. WinSCP)? Show us its log! Do you have any special characters in the credentials? — Martin Prikryl, Mar 17 '17 at 14:38
@MartinPrikryl my credentials are correct. I enabled SSL and it works fine now. Thanks for the response. — JustAnAverageSQLuser, Mar 20 '17 at 08:54

Try This:

Try

        Dim ftp_webrequest As FtpWebRequest = DirectCast(WebRequest.Create("ftp://domainname/filename"), FtpWebRequest)


        With ftp_webrequest
            .EnableSsl = False
            .UsePassive = False
            .Credentials = New NetworkCredential("username", "password")
            .Method = WebRequestMethods.Ftp.UploadFile
        End With
        Dim file() As Byte = System.IO.File.ReadAllBytes("filepath")

        Dim strz As System.IO.Stream = ftp_webrequest.GetRequestStream()
        strz.Write(file, 0, file.Length)
        strz.Close()
        strz.Dispose()

    Catch ex As Exception
        MessageBox.Show(ex.Message)
    End Try

Why should this help? There's hardly any difference to OP code. Except that you suggest use of active mode. What cannot help with this particular error; and will likely introduce even more problems. — Martin Prikryl, Mar 17 '17 at 17:05
Hi, I solved this, I had to Enable SSL for it to work. Thanks — JustAnAverageSQLuser, Mar 20 '17 at 08:53
