I can connect from macOS to a newly installed VPS (Ubuntu Server 24.04) via SSH and also with Transmit app, using username/password authentication. But when I try to create a new Server connection with Lifeboat (Build 250), Test and Connection fail, with this error message popping up.
Does anyone have an idea why this could fail?
I have some ideas for things to try, but I don’t see this problem with Ubuntu 24.04 on Digital Ocean. Could you reach out privately with connection details that I may test the issue? <support@strawberrysw.com>
Thanks!

I found the culprit! There was a file /etc/ssh/sshd_config.d/60-cloudimg-settings.conf which was overriding settings from /etc/ssh/sshd_config. After deleting this file, everything is working as expected.

The Ubuntu image provided by Oracle OCI came with /etc/ssh/sshd_config.d/60-cloudimg-settings.conf, which overrides the PasswordAuthentication setting with no.
At one point I was allowing root login with password, and tried to use root/password to login from Lifeboat, which was prevented by the setting in the mentioned file. However, I was able to login as root over ssh from macOS terminal … I don’t know why this was possible at that moment.
In the meantime I switched to a SSH key based authentication and switched off PasswordAuthentication. This works now for Lifeboat, Transmit and terminal access.
ChatGPT helped me to clean up my server, to generate keys and to enable key based access only.
