Hi all,

I’ve migrated my server recently and updated all DNS records accordingly.
If I query CloudFlare, OpenDNS, Google, the records come out correct.

When I run the ACME container it always finds wrong IP’s.
I’ve tried clearing unbound container cache, no success, the error keeps the same.

docker-compose exec unbound-mailcow unbound-control dump_cache

These AAAA records haven’t existed for around 24 hours. I can’t get those records from anywhere on our network (or from outside) except on the mailcow machine that keeps returning wrong records and failing getting the certificates.
