ECDSA host key for IP地址 has changed and you have requested strict checking. Host key verif错误解决

我用Hexo在服务器部署了博客，今天发现博客无法更新，并提示了如下错误

nothing to commit, working tree clean
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    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
SHA256:3TUqLv4nWCtUAXvMFo1gMk5UDkHm8oPszTLNeQJz4nM.
Please contact your system administrator.
Add correct host key in /c/Users/Administrator/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /c/Users/Administrator/.ssh/known_hosts:2
ECDSA host key for IP地址 has changed and you have requested strict checking.

and the repository exists.

[41mFATAL[49m Something's wrong. Maybe you can find the solution here: [4mhttps://hexo.io/docs/troubleshooting.html[24m

这里面，有一句很关键。

ECDSA host key for IP地址 has changed and you have requested strict checking.
Host key verification failed.

二、解决问题
解决问题也很简单：

ssh-keygen -R 你要访问的IP地址

D:\Myblog\blog>ssh-keygen -R IP地址
# Host IP地址 found: line 2
C:\Users\Administrator/.ssh/known_hosts updated.
