SSH accepts key but SSHFS doesn't

.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}

From my mac, I can ssh to an ubuntu machine without a problem.

The key is under my ~/.ssh/known_hosts.

When I try to sshfs to the same ip i get:

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

@    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:klJ1Y+1p8LdZuhukPrdpIOlolC05sX628n9owaM4DZY.

Please contact your system administrator.

Add correct host key in /var/root/.ssh/known_hosts to get rid of this message.

Offending ECDSA key in /var/root/.ssh/known_hosts:4

ECDSA host key for xx.xx.xx.xx has changed and you have requested strict checking.

Host key verification failed.

remote host has disconnected

The key mentioned on the log is not the one I have on known_hosts for this IP, is that right?

You're mounting sshfs from root or using sudo, while ssh is called with your normal user.

So sshfs Host key is not in ~/.ssh/known_hosts, but /var/root/.ssh/known_hosts.

Remove line 4 of that file and it will work:

sudo sed -i '4d' /var/root/.ssh/known_hosts

Alternatively, run sshfs with your normal user without sudo.
