Unable to upload files to a specified SFTP location

Question

My Code(few data are intentionally changed as "xxx.." for security reason ):-

public void SFtp_Connect()
{

        Sftp sftp = new Sftp();
        //sftp.Connect("xxx.xxx.x.xx", 22);
        //sftp.Login("xxx", "xxx");

        ////string sourceFilePath = @"C:\testFile\";
        //string sourceFilePath = @"C:\test_ftp\ExportList";
        //string targetPath = @"Test_Sftp";
        //string targetFilename = "";

        //sftp.Connect("xxx.xxx.com", 22);
        //sftp.Login("xxx", "xxx");

        sftp.Connect("xx.xxx.xx.xx", 22);
        sftp.Login("xxx", "xxx");

        string sourceFilePath = @"C:\Test\ExportList";
        string targetPath = @"/out/reports";
        string targetFilename = "";

        try
        {

            foreach (string UploadFile in Files)
            {
                //if (!sftp.DirectoryExists(targetPath))
                    //sftp.CreateDirectory(targetPath);

                sourceFilePath = sourceFilePath + "\\" + UploadFile;
                targetFilename = targetFilename + UploadFile;

                sftp.GetFile(sourceFilePath, UploadFile);                    
                //sftp.PutFile(sourceFilePath, targetPath + "/" + targetFilename);                   
            }
        }
        catch (Exception e)
        {
            throw e;
        }

        sftp.Disconnect();
    }

Error I got :-

Answer 1

Does the error occurs every time you try to login or occasionally?

Can you please post here or send us (to support@rebex.net) the communication log for analysis?

It can be created like this:

sftp.LogWriter = new Rebex.FileLogWriter(@"c:\Test\log.txt", Rebex.LogLevel.Debug);

Comments

this occurs every time we tried to establish connection with sftp server. exception occurs at the of getfile and putfile() call.

Below is the communication log :-
----------------------------------------------------------
2017-02-23 16:22:29.950 INFO Sftp(1) Command: SSH_FXP_STAT (2, '/out/reports')
2017-02-23 16:22:30.271 INFO Sftp(1) Response: SSH_FXP_ATTRS (2)

It seems you are trying to download a directory '/out/reports' but you are calling the sftp.GetFile method. Is it correct?
