Hey all, I've managed to open an FTP connection to Citrix Sharefile on Port 21, but when I change to Port 990, it comes back with Control channel unexpectedly closed ('' read so far).
I'm new to this library, and all I've done is use the following code:
'Open FTP connection
Dim ftp As New EnterpriseDT.Net.Ftp.SecureFTPConnection
EnterpriseDT.Util.Debug.Logger.CurrentLevel = EnterpriseDT.Util.Debug.Level.ALL
ftp.ServerAddress = My.Settings.FtpServer
ftp.ServerPort = 990
ftp.UserName = My.Settings.FtpUser
ftp.Password = My.Settings.FtpPassword
When changed to Port 21, this works perfectly. I should also point out that using FileZilla to connect on Port 990 works fine. I'm hoping that I'm just missing a property or something - help please?!
Here is what comes back when I attempt to open a connection on Port 990:
