	Hi, 

	I'm using ComponentPro.Sftp libraries in our C# application to connect to a remote server for sending and receiving files. 

	What is Successfully working: 

	       1. Connecting to remote server using public/private key authentication

	       2. Sending files after successful connection to remote server

	       3. Viewing files, changing directories on remote server

	 

	Libraries: 

	      1. ComponentPro.Common.dll (v 6.8.40.4155)

	      2. ComponentPro.FileSystem.dll (v 6.8.40.4155)

	      3. ComponentPro.Network.dll (v 6.8.40.4155)

	      4. ComponentPro.Sftp.dll (v 6.8.40.4155)

	 

	Things that are not working:

	       1. After we connect to remote server to fetch/get the file(flat file): Our application(using componentPro libraries) gets the file successfully and then application fails. So, after successful connection, we get the file on our local machine/server and after that our application catches exception of type "ComponentPro.Net.SftpException: Failure; Failure". 

	We included "ComponentPro.Diagnostics.XTrace" loggin to Verbose level and following is the result of it:
