WinSCP version used 5.13.3
I have a PowerShell script that does sftp files to a remote server.
Intermittently I get:
Timeout waiting for WinSCP to respond
Tried setting SessionOptions.Timeout property, which did not help either ...any leads?
Session log....says below...

< 2019-12-19 11:30:45.825 Script: Host is not communicating for more than 15 seconds.
< 2019-12-19 11:30:45.825 Still waiting...
< 2019-12-19 11:30:45.825 Note: If the problem repeats, try turning off 'Optimize connection buffer size'.
< 2019-12-19 11:30:45.825 Warning: Aborting this operation will close connection!
Turning off Optimize connection buffer size worked for my case. https://winscp.net/eng/docs/rawsettings
