SSH Login error from script connection

I've used WinSCP for a number of years without any issues. I've just created a new connection which works perfectly from the GUI but when I use the command line it issues an error and will not connect, error is -
Prompt (username, "SSH login name", <no instructions>, "login as: ")
The private key authenticates but it is not able to use the username for some reason. All other connections that use the same method work fine?

Re: SSH Login error from script connection

Please attach a full session log file showing the problem (using the latest version of WinSCP).
