  ui.err(#{ui.color("TO FIX THIS ERROR:", :bold)}If the server you are connecting to uses a self-signed certificate, you mustconfigure chef to trust that server's certificate.By default, the certificate is stored in the following location on the hostwhere your chef-server runs:  /var/opt/chef-server/nginx/ca/SERVER_HOSTNAME.crtCopy that file to you trusted_certs_dir (currently: #{configuration.trusted_certs_dir})using SSH/SCP or some other secure method, then re-run this command to confirmthat the server's certificate is now trusted.)

If youare able to connect to this server using the hostname #{cn}instead of #{host}, then you can resolve this issue by updating chef_server_urlin your configuration file.If you are not able to connect to the server using the hostname #{cn}you will have to update the certificate on the server to use the correct hostname.)
