NextDNS (ad blocker) breaks Nuki Bridge communication

Hi all,

I am using NextDNS on my iPhone to block ads.
If enabled, I cannot reach the Nuki Bridge via the Internet.
Disabling NextDNS makes it working again.

I do not see any blocked requests in the NextDNS protocol, so not sure why this happens

In case somebody else is having the same issue…
This situation only occurs in IPv6 only networks and is related to a DNS64+NAT64 implementation.

Workaround is to use a dual stack implementation with IPv4 & IPv6.
