Thanks. That got me on to the right track :)
Thanks. For some reason I get a different error message in that version.
Server sent command exit status 127
Cannot initialize SFTP protocol. Is the host running an SFTP server?
Doing a google, I came across:
For me it was client configuration fault. 127 code means that command wasnt found. I changed WinSCP config to use "/bin/sftp-server" instead of "default" by mistake. Check your client config.
Sure enough, if I change the setting in Advanced > SFTP > SFT Server to /bin/sftp-server , then it works! Not ideal, but at least I have a work-around.
Looking at the versions, I have 5.9.5
Hopefully this will help someone else in the future :)
