native ddclient not functioning for IPv4 CloudFlare

[akp55]

Hello friends,
    i'm not really sure where to start poking to figure out what went side was, but for whatever reason my DynamicDNS updating broke on 3/3/2026.  The native client was going and setting the A record with a random ipv4 address from cloudflare.  the client was configured with 2 entries.  one for the A record (monitoring WAN), the other for the AAAA record (monitoring a LAN if w/ pd).  the ipv6 client/thread would run and update both the A and AAAA record.  switching back to normal ddclient seems to have resolved the issue.  i'm more interesting in figure out why it happened and what i can do to fix it.  any tips/pointers would be greatly appreciated.

thanks
