@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
The ECDSA host key for raspberrypi.local has changed,
and the key for the corresponding IP address 192.168.3.12

DNS SPOOFING is happening or the IP address for the host
and its host key have changed at the same time.
Offending key for IP in /home/fseigojp/.ssh/known_hosts:1

Offending ECDSA key in /home/fseigojp/.ssh/known_hosts:3
remove with:
ssh-keygen -f "/home/fseigojp/.ssh/known_hosts" -R "raspberrypi.local"
ECDSA host key for raspberrypi.local has changed and you have requested strict checking.
