I am using WinSCP (v. 5.6.2). I am having a problem while using WinSCONet.dll. I am using this dll to download files from SFTP site in SSIS package. after deployment it works correctly for some days then, it start giving the error:

Please attach a full debug log file showing the problem (using the latest version of WinSCP).

To generate log file, set Session.DebugLogPath. Submit the log with your post as an attachment. If you do not want to post the log publicly, you can mark the attachment as private.

Also, isn't there any other instance of a scheduled task (either the assembly or WinSCP scripting) using older version of WinSCP.
