The same host through PuTTY, with the same credentials:

login as: root
Keyboard-interactive authentication prompts from server:
| Password for root@freebsd131:
End of keyboard-interactive prompts from server
Last login: Sun Nov  6 10:44:41 2022 from 192.168.1.32

Research direction

Start with the reported authentication exception and compare SSH.NET's public-key and keyboard-interactive behavior with the successful PuTTY transcript. Reproduce the connection against FreeBSD 13.1 using the same credentials; done means SSH.NET completes keyboard-interactive password authentication.
