Removing the empty line in the script fixed this. Thanks for the assistance!

It behaves somehow mysteriously. I cannot reproduce it.
But as I've posted above, I suspect the format of the batch file. The empty line cannot be there:

Normally WinSCP won't even see the commands after the empty line, as the batch file would consider them to be separate command, not belonging to WinSCP.
I can see in the log that WinSCP actually gets them. I assume it's because that in the actual batch file, the whitespaces are somehow non-standard.

Thanks for the guidance

Both the code and the log are incomplete. It's hard to help then.

I can only point you to:
Why are some WinSCP scripting commands specified in a batch file not executed/failing?
(particularly to the "New-line Escaping" section)

If you need further help, please post complete code and log.

I'm trying figure out what the problem is with this script. I'm able to transfer a file with GUI – and used the "Generate Code" for the session as a basis for the script.
Authentication is working fine but the target file won't download. I'm not sure if there's a particular parameter to add for timeout or something. Any assistance in pointing me to next steps would be greatly appreciated.
