DNS-OMATIC issue

[macster2075]

Hello,
I have a dnsomactic account and would like to use as the ddns service. I am unable to connect to my OpenVPN app on my iphone.
I was told by someone in the Asus forum that I need to edit the config file and replace the IP from the WAN with the dnsomatic host name which is all.dnsomatic.com, but it still will not connect.

the config file looks like this..
client
dev tun
proto udp
remote all.dnsomatic.com 1194
resolv-retry infinite
nobind
float
ncp-ciphers AES-256-GCM:AES-128-GCM:AES-256-CBC:AES-128-CBC
keepalive 15 60
auth-user-pass
remote-cert-tls server

does this look correct?
If not, what do I need to change?

Thanks.
