File Transfer fails on GrassValley K2 server.

I am not able to transfer local file to Grassvalley K2 server. Sample code is as below private void uploadFiles() { try { Ftp client = new Ftp(); client.Connect(serveraddress.Text); string auth = client.Authenticate(username.Text, password.Text); client.Passive = false; ComponentPro.IO.FileInfoCollection collection;//= client.ListDirectory(); // Set the log level. ComponentPro.Diagnostics.XTrace.Level = ComponentPro.Diagnostics.TraceEventType.Verbose; // Add the UltimateTextWriterTraceListener listener to write to a file. ComponentPro.Diagnostics.XTrace.Listeners.Add( new ComponentPro.Diagnostics.UltimateTextWriterTraceListener("c:\\temp\\log.log")); // You can also write log to a Console window with the following code: ComponentPro.Diagnostics.XTrace.Listeners.Add(new ComponentPro.Diagnostics.UltimateConsoleTraceListener()); string dirname = @"GXF/default"; string[] strsplit = dirname.Split('/'); foreach (var diritem in strsplit) { collection = client.ListDirectory(); bool bln = collection.Any(x => x.IsDirectory && x.Name == diritem); if (bln == false) { client.CreateDirectory(diritem); } client.SetCurrentDirectory(diritem); } List files = new List() { "SSIM-S2.gxf" }; ComponentPro.IO.FileSystemTransferStatistics stat = client.UploadFiles(@"C:\Temp", files, client.GetCurrentDirectory(), new ComponentPro.IO.TransferOptions(), 1, true); // Disconnect. client.Disconnect(); } catch (Exception ex) { MessageBox.Show(ex.Message); } } Log generated is as below Ftp: 1, Thread Id: 0 [05-23-2018 15:20:12.74] Information - Command: PWD Ftp: 1, Thread Id: 0 [05-23-2018 15:20:13.03] Information - Response: 257 "V:/" is current directory.
