      Could not resolve IP address for the GDK hostname `#{hostname}`
      Is it set up in `/etc/hosts`?
    MESSAGE
  end

  <<~MESSAGE
    The GDK hostname `#{hostname}` resolves to the IP addresses #{hostname_ips.join(', ')}.
    The listen_address defined in your GDK config is `#{listen_address}`.
    You should make sure that the two match.

    Either fix the IP address in `/etc/hosts` to match #{listen_address}, or run:

       #{hostname_ips.map { |ip| "gdk config set listen_address #{ip}" }.join("\n")}
