Problem with SSH server on 12.0 release, is it a bug?

[voravit]

On 12.0 release, SSH service runs but it closes the connection before authentication when ssh to 127.0.0.1.
I tried on 11.1 release, and it works fine.
Is there something new in 12.0 release that I missed or is it a bug?

Both 11.1 and 12.0 run OpenSSH_8.1p1. But 11.1 uses OpenSSL 1.1.1f while 12.0 uses OpenSSL 1.1.1j.
The sshd_config is copied from sshd_config.orig (and I set a new password for tc user).
The output messages of "ssh -vvv 127.0.0.1" are nearly identical and do not provide a reason why the connection closes on 12.0.
The attached file is the diff between the output messages.

openssh updated - it appears to fix the problem, but maybe you could test?

Thank you for your quick response.
With OpenSSH_8.4p1, I can ssh to 127.0.0.1 now.
