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:lB+btCFd0bHTdG4h2l56B82XaNwZ6Owi7eOq9f1zATM.
Please contact your system administrator.
Add correct host key in /home/csmith/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /home/csmith/.ssh/known_hosts:1196
  remove with:
  ssh-keygen -f "/home/csmith/.ssh/known_hosts" -R ec2-18-219-25-147.us-east-2.compute.amazonaws.com
ECDSA host key for ec2-18-219-25-147.us-east-2.compute.amazonaws.com has changed and you have requested strict checking.
