I updated my main Deco to a new X80 router from a previously very reliable X60 that is now relegated to a regular hotspot on my mesh network. Everything is working well except my existing DDNS domain at tplinkdns.com is no longer available and I am unable to register a new one - I get a "Failed to save your settings - please try again later" message on attempting to update the domain name.

Grateful for any insights..
