Just keep getting the abuse message back from dnsomatic

So I've configured my router to send updates to dnsomatic.

But I keep getting a message in my router (Asus RT-AC66U) logs: host "all.dnsomatic.com" has been blocked for abuse

I'm wanting to keep opendns updated with my ip address so it doesn't matter what hostname I provide.

NOw if I go direct to the updates.dnsomatic.com address with my relevant details I simply get the word "abuse" back so I suspect the reason the router is indicating this is because I get abuse back when I go direct.

Even if I include all.dnsomatic.com as the hostname, as the docs indicate, I still get this "abuse" message and if I don't send the hostname when I go direct I still get this abuse message.

Am I updating too often? I don't think I can reduce the frequency of the updates coming from the router though :(
