Re: WinSCP Appears to Ignore $session.Timeout
The
Session.Timeout is of type TimeSpan. When converting an integer to the TimeSpan, the PowerShell treats the integer value as microseconds (aka ticks), not as seconds. You want this instead:
$session.Timeout = New-TimeSpan -Seconds 120

Basic Info
WinSCP version: 5.17.6 (Build 10516). Unfortunately, upgrading to a more recent version is not an option for us at this point due to our update cycle.
Windows: Windows Server 2016 Standard version 1607
Transfer Protocol: SFTP with private key authentication

$session.Timeout parameter and set it to 120, but it appears that WinSCP is now exiting with an error immediately. My script is below, and I will also attach the session log and debug log.
