It means you have reinstalled your local computer, and recreated the local
key. The remote server just says 'oh, oh you're lying to me. the first time
you came here that way , you said you'll give another fingerprint (the long
string) than the one you're giving to me now. You must not be you. Stop
lying, and I'll talk with you again, BYE.'

You have to find an alternative way to connect to this server, to open
/root/.ssh/known_hosts. And to remove the first line. You'll go again
through the fingerprint exchange process again.
