@hareem.mughis: This does not seem to be related to the issue this thread is about. Please start your own and attach a full session log file showing the problem (using the latest version of WinSCP).

I have created a console app which is running the WinSCP to transfer the data. When I run it manually it works fine data get transfer. But when I setup the a schedule for my application in the task scheduler, it run successfully but the data doesn't get transfer. The WinSCP version I am using is 5.19.5

You might have this problem:
Issue 2005 – Hang when running under Task Scheduler or a similar service with session logging enabled
I'm sending you an email with a development version of WinSCP to the address you have used to register on this forum.

I have .NET console application which use WinSCP .NET assembly. I created task in Task Scheduler to run that application on daily basis. When starting that task manually everything works OK, every time. When I let scheduler do the the work I get error message:

Timeout waiting for WinSCP to respond - WinSCP has not responded in time. There was no output. Response log file C:\Users\aaa\AppData\Local\Temp\wscp3FC8.029531C8.tmp was not created. This could indicate lack of write permissions to the log folder or problems starting WinSCP itself.

If I schedule computer restart before this task run it will run without problems, but the next day (without computer restart) it will fail again. So it works only with computer restart prior the task run. I read Bug 996, but don't have on that computer WinSCP versions other than 5.19.1.
