There's nothing more to suggest that what is already in the answer on Super User.

Did you try to increase the timeout? Session.Timeout

Hi

Everyday I got tasks that using powershell with WinSCP to automate downloading files from clients' sftp, they all work fine on most day, except Saturday (between 7:00 to 17:20)

the task that I run is basically looking for new files and then download it, it starts at 5:00 and repeat every 5 minutes for 12hrs in task scheduler and run as Administrator

On Saturday, it starts well (mean I got normal message) at 5:00am and until 7:00, I got this error message for every 5 minutes until 17:20

Error message: Timeout waiting for WinSCP to respond - WinSCP has not responded in time (response log file C:\Users\\AppData\Local\Temp\wscp.tmp was not created). This could indicate lack of write permissions to the log folder or problems starting WinSCP itself.

and after 17:20, I got the normal message:

'Synchronise the link file folder

WinSCP.SynchronizationResult

No files synchronised

COMPLETE'

I only got those error message on Saturday

do anyone know why and know how to fix it?

Thank you very much
