Question Disconnection in 0 seconds when connecting to ssh as a non-root user

[Yuki]

Server operating system version

Ubuntu 22.04.1 LTS

Plesk version and microupdate number

Plesk Obsidian 18.0.50

I have a server that is managed by Plesk.

When I connect to it via SSH as root, it works fine.
However, when I create a new account and connect to SSH as a non-root user, I am forced to disconnect in 0 seconds.
The connection is established without any problem.

What settings are considered effective in such a case?
Please let me know if anyone can help.

The server information is as follows

OS: Ubuntu 22.04.1 LTS
Product: Plesk Obsidian 18.0.50 update #1, last updated on 2023/02/10 13:07

Thanks for the reply.

Sorry for the delay in confirming.

I would like to log in as a non-root user.

I am looking into the fact that the login is established and then immediately disconnected as if it is a security related issue.

Please let me know if you know of any other information.

I appreciate your support and I will keep you posted on my progress.
