@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
SHA256:oDIfDjTUBaNHma5tTeNnbVf86HX24EgkNyijxG3IXhQ.
Please contact your system administrator.
Add correct host key in /root/.ssh/known_hosts to get rid of this message.
Offending RSA key in /root/.ssh/known_hosts:28
remove with:
ssh-keygen -f "/root/.ssh/known_hosts" -R "[170.80.84.10]:22023"
Password authentication is disabled to avoid man-in-the-middle attacks.
Keyboard-interactive authentication is disabled to avoid man-in-the-middle attacks.
root@170.80.84.10: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).

Era só remover o caminho /root/.ssh/known_hosts
comando rm -f /root/.ssh/known_hosts

A melhor solução nem seria remover todo o arquivo known_hosts e sim apenas o registro que está alterado. A própria mensagem de erro já aponta a solução:

# ssh-keygen -f "/root/.ssh/known_hosts" -R "[170.80.84.10]:22023"
