Hy you all

After the last update, I losta my configuratio tha turn on/off my Raspberry and turns on a Blue LED when Volumio is on.

To remade it, I have to make a SSH conection, but when I try to connect, I receive this message:

MacBook-Air-de-Guilherme:~ guilherme$ SSH PI@192.168.211.1
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
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:mVI5SPfT7HMBM80ECmpVT9lZi9N4wfKJfJ8fffQEO+s.
Please contact your system administrator.
Add correct host key in /Users/guilherme/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /Users/guilherme/.ssh/known_hosts:1
ECDSA host key for 192.168.211.1 has changed and you have requested strict checking.
Host key verification failed.

I tried to connect by LAN and by HotSpot and in both cases the message was the same.

PS: The SSH was enabled via DEV page.

Can someboddy help-me with this please?

OK, I solved this problem using this command:

ssh-keygen -R <volumio_IP>

But now I heve another problem. When ssh connection is make, and the passoword ( volumio ) is entered, then I receive a message that the passord is wrong. See above:

MacBook-Air-de-Guilherme:~ guilherme$ SSH VOLUMIO@192.168.15.3
The authenticity of host ‘192.168.15.3 (192.168.15.3)’ can’t be established.
ECDSA key fingerprint is SHA256:mVI5SPfT7HMBM80ECmpVT9lZi9N4wfKJfJ8fffQEO+s.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added ‘192.168.15.3’ (ECDSA) to the list of known hosts.
