Encryption failed because its identity could not be confirmed

Question

Hello. I've been having this issue from time to time; I'm trying to connect to another computer which has both *Remote Management* and *Remote Login* activated. On this computer I got *Encrypt all network data (more secure)*, and for some reason after I try to connect to another computer (that has Remote Login activated) I keep getting this error:
Connection failed because its identity could not be confirmed. This could represent a security problem, or your SSH known_hosts file may be out of date.
Disable the "Encrypt all network data" security setting or update your SSH known_hosts file.
How would I update the SSH known_hosts file? And I thought all this was made automatically? I used to be able to do this before, but its not working lately.

Just found the answer:

On the admin computer (Mac OS X client computer), choose Go to Folder from the Finder's Go menu.
Type in the path name to your home folder adding /.ssh to the end of the path. example:
/Users/username/.ssh where username is your short name.
Inside the .ssh folder, open the known_hosts file.
Locate the Servers IP and or its fully qualified Domain name and delete it and the associated characters.Example:
example.example.com,192.104.192.118 ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAIEAutfhNudfFzZ00dyrU5O7/Y1wYhkhVJTSlNLqFROuvkmsB39Y8/> q47cQzdFqRfxsAlirDQKWW2xfr8qAKormuz7fT7so1myuanG24IYPwWmnZdLa3MdQ2zrWDkw672TZUT PBErrZYetej+KnU500mOcvdHjsj0SyPkqVRdPAXs=
Note: These characters can wrap to several lines.
Save and close the file.
