I have long used DNS-O-Matic top update my public IP for use of OpenDNS on my network for content filtering.

After signing up for dynu and transferring my domain name here, i added Dynu as a service and in DNS-O-MATIC dashboard it says "waiting for first update" for days. I manually input the public IP the first time and it has since changed. OpenDNS updated, but Dynu did not. Still says waiting for first update.

Any tips or help? I have confirmed that I am using the same username and login as i input on the dynu service setup with DNS-O-Matic, several times. I used idahobk.com under the "domain" setting with DNS-O-Matic for Dynu. perhaps that's not right?

Thanks in advance.
