$exception {"Failure"} Renci.SshNet.Common.SshException I get exception on downloading the files

Hi team

I'm using the below code for downloading files from the SFTP server.

` DataLakeFileSystemClient fileSystemClient = new DataLakeFileSystemClient(connectionString, "container");

        DataLakeDirectoryClient processDirectory = fileSystemClient.GetDirectoryClient("testProcessDir");


        using (var sftp = new SftpClient(host, username, password))
        {
            sftp.Connect();
            var files = sftp.ListDirectory(remoteDirectory);

            foreach (var file in files)
            {
                string remoteFileName = file.Name;
                if (!file.Name.StartsWith(".") && (DateTime.UtcNow - file.LastWriteTimeUtc).TotalHours < 1)
                {
                    DataLakeFileClient newfile = processDirectory.CreateFile(file.Name);

                    using (Stream stream = newfile.OpenWrite(overwrite: true))
                    {


                        sftp.DownloadFile(remoteDirectory + remoteFileName, stream);
                    }
                }
            }`

After downloading 1 or few files it gives execption as $exception {"Failure"} Renci.SshNet.Common.SshException

Please suggest something with which I could download all the files.

Thanks,

Start with the stack trace at Renci.SshNet.Sftp.SftpFileReader.Read() and SftpClient.DownloadFile(), then inspect the caller at Program.cs lines 75 and 15. Reproduce the loop against an equivalent SFTP server and determine why downloading multiple files raises SshException("Failure"); done means identifying a reproducible cause or required diagnostic details.
