Add -timeout=60 switch to the open command:

https://winscp.net/eng/docs/scriptcommand_open#timeout

REM connect to ftp via winscp and runs syncronization
REM winscp syntax open ftp://<username>@<host> -explicittls
winscp.com /log="OrganizationEXEDownload.log" /command ^
"open ftp://username:Password.organization.org/ -explicittls -rawsettings MinTlsVersion=10 MaxTlsVersion=12 -timeout=60"^
"synchronize local . /Organization750 " ^
"exit"

also let me know if i should delete this and move this to the scripting thread instead realize that might have been more appropriate.

Hi
Let me start by apologizing for what might be a easy and silly question.
I inherited support of a PowerShell script that opens a WinSCP sessions to an FTP to download and replace some files daily.

Recently came to the conclusion since both sender and receiver servers are slow combined with some firewalls rules the session time out.
So I need to increase session timeout.

Tried to add timeout command with help from a colleague, that did not work.
After checking similar post I have realized this ($session.Timeout = New-TimeSpan -Seconds 120) seems to be the best solution.
But I'm still terrible unsure where in the script this parameter goes to be applied since our formating seems to be different that most.

I have added both old and last attempt as file and copypasted it below.

New (didn't work)
