WinSCP separate session for duplicating files

[NOYB]

WinSCP opens a separate ssh session for direct duplication of remote files.

On OPNsense box "starting the session..." fails.

Works fine on other FreeBSD boxes.

Is there something specific about the OPNsense that would cause this?

Thanks

Maybe a setting that sshd_config is not having and therefore setting to a wrong by default?

Can't be sure. Might be best to start sshd manually in verbose mode to see what happens on the OPNsense end.


Cheers,
