NextDNS not updating IP from TP Link DDNS.

I use NextDNS with TP-Link Deco XE75.

The router accesses Internet via PPPoE. IPv6 is enabled. It has been set to restart every day at 4.45AM, since the IP Lease time is 1 day. But every day morning, I wake up and find that NextDNS is configured with no profile linked, and I have to manually refresh the IP.

I had this problem since the beginning, so I created a fresh profile, it worked for 1 day and now it's back to itself. This is not an issue with the DDNS service because I manually pinged it using the tracert command in Terminal and it was always showing the right IP.

I wonder why this problem, which has been mentioned for over 1 year in many other forums is still a thing. This is an issue with basic functionality from a paid service. Please fix this issue.

    You said ipv6 is enabled, but do you have an ipv6 address?   If so, configure the IPv6 dns servers listed in your set up tab.  
     

     If you have an ipv6 address you won’t need to bother with the ipv4 linking.  
     

    why restart everyday?  An ipv4 address issued by DHCP should automatically renew itself when 50% of the lease time is up.   If you have an ipv4 address you might be giving up the lease by restarting the router.

       I do have an IPv6 address. And I have configured the IPv6 DNS servers too. But unless and untill I configure IPv4 DNS, NextDNS will say I have no linked profile.

      My public IP lease time is 24 hours, I have a PPPoE connection. My carrier doesn't use CGNAT. I restart the router daily at 3AM, so that the IP won't reset in day time and it does cause momentary connection drop. 

      The original problem is NextDNS not updating the IPv4 from DDNS server, so far I haven't sensed a solution in your otherwise long reply.

       linked profile shouldn’t be necessary if you have ipv6.   With ipv6 they givean ip at their end which is unique to your profile.   With ipv4 there’s not enough addresses to give everyone their own, that’s why it needs to be linked.   You can ignore the link process
