SSH Connector Unsupported SFTP Version

I am using KNIME 4.5.1.

I have a workflow that was using the SSH Connector successfully to connect to an SFTP server.

I updated this node to connect to a replacement SFTP server.

Now I receive Unsupported sftp Version 0 (SshException):

However, the same exact connection setup for this server is successful in the SSH Connector (Legacy) node and allows me to download the target file.
