Delete the remote IP, in ssh and then revisit it, and always prompt for an error when it comes to entering the password.

encountered SSH login failure: Host key verification failed.
my action:
delete the corresponding IP, in Know--host and reconnect.
but there is a problem: the
password is wrong, and then let me re-enter it. This happens when the other Permission denied,please try again.
is also connected to the same IP.
my action is:
ssh-keygen-R [hostname]
then reconnect and find that the password is still wrong. Let me re-enter it.
what is this situation?
Thank you
