Can no longer ssh into mycloud

i currently am running macOS catalina.
the wdmycloud is currently running v04.05.00-342 (an older 4TB model).

the shell in macOS 10.15 has been changed to zsh.

when I try to ssh usually the below command works. This time I am getting different output:
(i have edited out some personal info and the SHA256)

username@mbp ~ % ssh root@192.168.1.160
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    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 RSA key sent by the remote host is
SHA256: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Please contact your system administrator.
Add correct host key in /Users/username/.ssh/known_hosts to get rid of this message.
Offending RSA key in /Users/username/.ssh/known_hosts:1
RSA host key for 192.168.1.160 has changed and you have requested strict checking.
Host key verification failed.
username@mbp ~ %

not sure what the problem might be … anyone have some ideas/suggestions ?

i was able to resolve this by searching around online for the same problem. it seems like the rsa key had changed probably after updating firmware of the mycloud
