这一类问题，一般都是你的known_hosts保存了网络身份验证证书，更换了环境去访问，就会被服务器拒绝。
按照错误提示的/c/Users/HASEE/.ssh/known_hosts，打开这个文件，把你访问的远程服务器的ip地址修改下即可。
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
SHA256:6ZDmazf+l+8cMDYOgXkKHKya0qM/09yjaDzq4FErkKE.
Please contact your system administrator.
Add correct host key in /c/Users/HASEE/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /c/Users/HASEE/.ssh/known_hosts:10
ECDSA host key for 10.70.59.252 has changed and you have requested strict checking.
Host key verification failed.
具体来说，打开方式就是
vim /c/Users/HASEE/.ssh/known_hosts
然后切换成insert模式进行修改
删除这个ip地址例如10.50.90.23 ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAxxxxxxxxxxxxxxx
后面对应的一大堆就是证书，把这一行都删除，包括ip地址。
再次访问，可以认为是首次访问
The authenticity of host '10.70.59.252 (10.70.59.252)' can't be established.
ECDSA key fingerprint is SHA256:6ZDmazf+l+8cMDYOgXkKHKya0qM/09yjaDzq4FErkKE.
Are you sure you want to continue connecting (yes/no/[fingerprint])?
你会发现known_hosts里面有个新的key
