Which is like using your key and it not opening a door. You could have the wrong door like you went to the wrong room or someone could have changed the locks. If someone gets a new door, e.g. reinstalls OpenSSH then it will generate a new private SSH key.
Of course, it's possible due to the way the Internet works someone could be pretending to be the server you are looking for.
The only way to tell the difference between the owner of the server getting a new "door" and someone "pretending" to be the server is to ask the person who owns the server.

33,856 PointsGood explanation. This happens to me a lot when I destroy and recreate a DO droplet and it provides the same IP address. I usually have to delete the .ssh folder so it will accept again.
