      Thanks for sharing the blog.

      I am receiving the following error while using private key authentication in the sender SFTP adapter.

      Exception received: com.jcraft.jsch.JSchException: inputstream is closed

      Any leads would be highly appreciated.

      PS: Using password based authentication i am able to successfully pick up files.
