My Server is Ubuntu 14.04.5 LTS and I am able to connect SSH in Putty, but not able to connect via WinSCP.

When I try to connect via WinSCP it gives below error:

Connection has been unexpectedly closed. server sent command exit status 127

This does not look like a programming question. It should go to Super User or a similar site (like AskUbuntu, where you have already asked it -- askubuntu.com/q/1111873/280048 ) Martin Prikryl Jan 22, 2019 at 8:33
