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 RSA key sent by the remote host is
SHA256:M+I2wvuU9NkNuky0XSWsdqS2N8+2sFUb8H66BxhTVtQ.
Please contact your system administrator.
Add correct host key in C:\\Users\\本地用户名/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in C:\\Users\\本地用户名/.ssh/known_hosts:4
RSA host key for 192.168.1.230 has changed and you have requested strict checking.
Host key verification failed.

解决方法

1. 找到用户目录下的.ssh目录，如：C:\Users\本地用户名\.ssh 。在该目录下有一个known_hosts文件，专门记录ssh过程中匹配的秘钥。
2. 编辑该文件，删除以不能连接的IP开头的整行内容，保存并退出。
3. 重新连接即可。
