Reset SRR60, now can't rejoin my netgear dynamic dns. Screen just refreshes and resets to blank.

I just completed updating my SRR60 and satellites to V2.6.2.200 firmware, and I reset the router to factory defaults.  When I try to re-enter my dynamic dns info, it accepts the data, blanks the screen, then refreshes the screen with the fields blank.  A 'Show Status' says that I'm not connected to dynamic dns.  No error messages.

I thought this may be related to the recent announcement from Netgear that they're no longer maintaining our dyndns service and have given it to no-ip.com to manage, with no-ip.com requiring a manual refresh every 30 days for free accounts.  However, I refreshed my account via them 5 days ago when I got an email from them, and it refreshed successfully.

Then I thought that I may need to re-enter my info into the Orbi Pro web config page, but specify no-ip.com instead of Netgear as the dyndns provider.   That results in the same blank page refresh.

I tried this on Firefox and Google Chrome on a linux machine.  I then tried it on Safari on my iphone, connected to my phone network and not my home network.  Same results.

I do not have a login to no-ip.com, as I assume my dynamic dns name is a free account and doesn't require it.  

No-ip.com certainly knows about the name ("blueskyretreat.netgear.com"), but since I don't have a login, I can't do anything other than refresh every 30 days.

I do not want to create a new dynamic dns account with no-ip as this would royally screw me.  I use my Orbi Pro in a business environment and cannot, at this stage, change my website URLs without serious impact to my customers and my business.

How do I re-connect my existing, current, valid dynamic dns address to my SRR60?
