Topic "Scheduled task failing"

I have a Windows Server 2003 R2 scheduled task invoking a batch file to upload some files to a vendor.

The batch file is as follows:
"C:\Program Files\WinSCP\WinSCP.exe" /console /script=d:\scripts\my-script.txt /log=d:\logs\my-logfile.log

The script is as follows:

option batch abort
option confirm on
open sftp://ftp-user:My_Passwd123@ftp4.RemoteDomain.com:22 -hostkey="ssh-rsa 1536 01:02:03:04:05:72:f6:71:ac:ab:da:1f:e2:3f:53:2f"
cd in/prod
lcd D:\Projects\AP\FileExport
option transfer binary
put *.*
close
exit

The WinSCP client is configured to store in INI file. We have initially logged on as the user whose context runs the Windows scheduled task, and when logging on the time/date stamp of the .INI file and the %appdata%/winscp.rnd were updated. The script runs fine when manually invoked. I'm concerned that the log file satates "Configuration: HKEY_CURRENT_USER" etc. since of course as a scheduled task, without that user logged on, there is not HKCU hive available for that user.

When we leave it to run by itself, it fails I believe while waiting to accept the host key - it just times out. I've tried increasing the timeout to 90 seconds. It takes 4-5 seconds to authenticate when manually running the batch job.

The log files look like this:

Further information: When it works, the log files show that I'm using an *.ini configuration. Yet I did nothing to change it. I'm currently rounding up my coworkers to accuse them of having changed this setting in the GUI - > Preferences > Storage > Windows Registry vs INI file.

All right, I've updated the batch file that calls the script, to include the path to the INI file:

Calling .bat file:
The batch file is as follows:
"C:\Program Files\WinSCP\WinSCP.exe" /console /ini=d:\scripts\my-script.ini /script=d:\scripts\my-script.txt /log=d:\logs\my-logfile.log

And the script still hangs. Here is the log output:

In reviewing the .ini file, I see that it has not been updated since 48 hours ago, so I am not certain how to verify that the host key is cached in there. I am afraid that this may be the issue. I have anonymized the hostnames, etc, but will email the .ini file in its original state if requested.

It's not related to the host key verification.
Have you tried increasing the timeout?

Yes, I've tried up to 90 seconds. When the task is run from the command line, or from the console, it runs in between 4 and 5 seconds every time. Changing timeout to 90 seconds merely makes it keep trying for 90 seconds, and then fails. Thank you.
