Just to add that I’ve fixed the situation. The mismatch was between my local RSA key stored in my PC. Just removed the keys with command:
$ ssh-keygen -R {ssh.server.ip.address}
After running got:
Host 192.168.xx.xx found: line 1 type RSA
/Users/MyUser/.ssh/known_hosts updated.
Original contents retained as /Users/MyUser/.ssh/known_hosts.old
After I was able to login normally.
