@qdm12 commented on GitHub (Jul 26, 2024):

I believe the problem comes from using "provider_ip": true. Since you have a ipv4+6 dual stack, dynu determines your ip address using ipv6, and so it compares it to the ipv6 set which is the same, and thus responds nochg. Basically, as soon as you have ipv6 and want to update ipv4 as well, you should not set "provider_ip": true, for all providers.

Anyway, on top of this workaround mentioned, I changed the program to just NOT use provider_ip at all, since it's kind of useless anyway, in commit 918df24488 (latest image and next release v2.8.0).
