OK, you need to contact your network administrator.
Guest

Nope. Tried several other SFTP clients. I can login via a webpage.
martin

No, it dies well before the key exchange. No data ever arrives from the server.
It's likely a firewall issue.
Can you SSH to that server from the Win2016 Server any way? WinSCP GUI? Any other SSH/SFTP client?
jima

I think it has something to do with the key exchange. This is the log of the workstation where it is successful. Compare the logs. It dies at the key exchange.

No. It gives the same error. It works fine from a workstations. Not Server software.

Does it work, when you run the batch file manually in a normal Windows session?

Simple Batch File being run from task scheduler

Winscp failing to connect from Win2016 Server

Trying to setup Winscp to run from batch file and upload file to vendor sftp site. Simple batch file:
start c:\winscp\winscp.exe /console /script=upload2.txt /log="g:\upload.log"

the script file has this in it:
open sftp://USERNAME:Password@VENDOR SITE/ -hostkey="ssh-dss 1024 9yhLnt/T9tfWZc10LbZsWefPPNMp3cDlqULcyOXdefE="

This works fine from a regular workstations running Windows 7,8 or 10.
The log file from the server gives me this:
