No ssh connection: REMOTE HOST IDENTIFICATION HAS CHANGED

When you try to connect using ssh in terminal to a remote host, if you get this message:
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    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 ECDSA key sent by the remote host is
SHA256:wJp/vYtoiAonG/LRyXK6fYuzcCb7WQZF1N9tlxVVOsg.
Please contact your system administrator.


you must edit this file:
sudo vi ~/.ssh/known_hosts
And remove the line corresponding to the faulty ip address.
