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
SHA256:36vsuYywBZkJ0W04SmMFKgSPvJk/FoUTCOkIytwSS1I.
Please contact your system administrator.
Add correct host key in /c/Users/86131/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /c/Users/86131/.ssh/known_hosts:21
ECDSA host key for 106.52.223.232 has changed and you have requested strict checking.
Host key verification failed.

碰到此问题只需要执行

vi ~/.ssh/known_hosts

然后删除里面的连接IP信息即可，比如我连接的是106.52.223.232，那我就删除这个ip的信息
