I can’t connect to SSH with the error “WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!”

Please delete the SSH host key of the SSH login destination host that is causing the error, and then try the SSH connection again.

To delete the SSH host key, enter the following command.

ssh-keygen -R ホスト名(sol.edu.cc.uec.ac.jpやssh.cc.uec.ac.jp等)

You can also delete the SSH host key by deleting the line for the relevant host in the ~/.ssh/known_hosts file with an editor.

This kind of error will be displayed if the SSH host key has been changed due to reasons such as server replacement.After deleting the host key, you can register a new SSH host key by checking the SSH connection destination and attempting the SSH connection again.
