Noip ddns not working orbi 20

[Phairplay]

Hi,
I've just purchased the orbi 20 and have everything set up expect my ddns.
I give it my host name (mydomain.com), user name and password. Yet it keeps saying my host name is incorrect


Could someone please help?

I originally set up a DDNS at No-IP.com.  Was surprised to find that the Orbi wanted the DDNS name to be "<mystuff>.mynetgear.com"

When you log into your No-IP.com account, what happens if you change the host name to that and then go back to Orbi and set up the DDNS again?

Noip have been hosting my person domain for 3yrs I've not set one up with netgear.

Everything was fine on my previous router, I set orbi up this weekend.
