Hi @Zurich0,

Are you using the OpenSSH config and authentication agent option in the SSH configuration? Did you try to connect to the server using the ssh command in the terminal? If you can connect to the server using the ssh command, you should be able to connect to the server using the SSH tunnel in the plugin.

Hi @AntonShuvaev , I am using OpenSSH_9.3p1, LibreSSL 3.3.6. I can connect the server using ssh command in the terminal, but can not connect the ssh from Elasticsearch plugin. And I try the idea self-contained database tools, it can also connect the server normally.

@Zurich0,

Thanks for the details, I will look into it.

I've added support for keyboard-interactive SSH authentication in 2023.2.4. Please update the plugin and let me know if it works for you.
