Hi AsusMy,

I'm using ASUS Router RTN-66U for the past 2 years and have no issues using the ASUS DDNS service.
Recently, I'm upgraded from Unifi VIP5 to Unifi 30 and also the ASUS firmware "3.0.0.4.378_9459".

This happened coincidently on this Monday. After the restart of the Unifi Modem and Router, I can't access the DDNS service anymore and will need to use ASUS NSLookup and type in the IP address instead of the DDNS hostname. Typing the IP address works, but will need to check this everytime I reboot the router.

Is there any settings which I need to reconfigure?
