WindowsのSSHよりUbuntuに接続しようとするがエラーとなる

C:\Users\user>ssh -l user 192.168.56.10

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:TjwyMDByj5j03WUAhHD7sFTs7APH0zcPrYuLfNVR7dA.
Please contact your system administrator.
Add correct host key in C:\\Users\\user/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in C:\\Users\\user/.ssh/known_hosts:3
ECDSA host key for 192.168.56.10 has changed and you have requested strict checking.
Host key verification failed.

→ 以前構築してた仮想マシンの情報が残っているため
接続元(Windows側)でキーを再構築する
"ssh-keygen -R 192.168.56.10"

再度SSHにて接続
→ 接続できた
