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:nlhtD9kmhjDTFTJRUcPVuMmn7bvvuD3VS5wHmUOWsE0.
Please contact your system administrator.
Add correct host key in /var/root/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /var/root/.ssh/known_hosts:27
ECDSA host key for ec2-15-206-161-217.ap-south-1.compute.amazonaws.com has changed and you have requested strict checking.
Host key verification failed.
Mukeshs-Air:~ mukeshchoudhary$ vi /var/root/.ssh/known_hosts
Mukeshs-Air:~ mukeshchoudhary$ vi /var/root/.ssh/known_hosts
Mukeshs-Air:~ mukeshchoudhary$ sudo -s
bash-3.2# vi /var/root/.ssh/known_hosts
bash-3.2# 


Just go to these steps and open "known_hosts" and edit your file that creating problem as above mentioned i had an issue with line no 27 so i just removed that host name and saved and now try again with new aws ssh key.
