Help debugging why SSH connector doesn't work while legacy one does

I have a fairly simple connection to an sftp server that uses nothing but username and password to get in. For some reason, it will only work in the “SSH Connection (legacy)” node and not with the newer SSH Connector. This is a big hassle since the file connection ports are not compatible with the file Transfer Files node.

Is there any way to see the output of ssh verbose logs to see if there is any indication of the problem? Any other troubleshooting I can do?
