OpenVPN Client connecto-to only accepts IP (not domain name)

Hi,
I’m trying to configure an Omnitik 5UPA to have an OpenVPN client that connects to a remote OpenVPN server (with dinamic IP), when I try to configure that, the Webfig doesn’t allow me to put “mydomain.com” at connect-to parameter (#PPP.Interface.new.OVPN_Client); only accepts IPs.

It’s a known RouterOS limitation?
Or I need to configure that using a terminal (telnet, ssh…)?

Thanks!

Install latest routeros version.
