Myślę, że możesz założyć, że ten klucz faktycznie się zmienił, bo się zmienia np. podczas reinstalacji serwera.
Wykonaj więc to co tam pisze.

Inne przyczyny zmiany klucza opisano np. tu https://serverfault.com/questions/537035...expectedly

    You have changed the host keys yourself, and didn't clear or update them on your client machines.
    This is the most common situation. Checksum the key files and be ABSOLUTELY CERTAIN they haven't changed.

    You have changed your SSH configuration to present (or request) a different key type than before.
    e.g. you previously wanted RSA or DSA keys, now you use ECDSA -- that's a "key change".
    If this is the case, verify and accept the new keys (or if this isn't what you wanted, undo the change).
    (It sounds like you're in situation #2 -- Undo your changes, restart sshd, and verify that things work as expected. If you haven't accepted the new keys anywhere undoing the change should make the error go away.)

    SOMEONE IS DOING SOMETHING NASTY
    The Man-in-the-Middle attack SSH warns you about has reared its ugly head. Someone is actively trying to intercept your communication to steal your private key or do something else you almost certainly don't want them to be doing.
