Timeout and transfer options appear to be ignored in WinSCP for PowerShell
Hey Team,
Versions: WinSCP Version 5.17.10 (Build 11087) (OS 10.0.14393 - Windows Server 2016 Standard)
So the main issue is that we are having disconnections between my end (source) and the client (destination). We constantly see this message in the logs
I tried to extend the timeout from 15 seconds with this line
And I've added the transfer options for turning off the optimize buffer size, but that seems to be ignored as well (based on the message above in the log)
But the log file shows that the timeout isn't working
I'll attach the WinSCP code I have in my script, and a session log as well.
