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:Z0O3MWVzRTmyZtixzbm8sUHAHsygdftbPrWZcme8ZGo.
Please contact your system administrator.
Add correct host key in /Users/cedric/.ssh/known_hosts to get rid of this message.

解决方案：
找到.ssh文件夹，一般默认地址在Users/cedric/中(cedric替换为本机用户名)
删除本机 .ssh/known_hosts文件中关于192.168.1.112（你需要连接的IP地址）公钥信息
或者直接删除.ssh/known_hosts文件
重新ssh，成功连接
