Hello Dear joohoi
Thanks for your great project.. Last week I setup this project on docker. and all run correctly and certificate produced.
But now does not work.
$ dig -t txt @auth.example.org d420c923-bbd7-4056-ab64-c3ca54c9b3cf.auth.example.org works correctly
$ dig _acme-challenge.mydomain.com CNAME works correctly
but
$dig _acme-challenge.mydomain.com TXT return a TXT from primiry DNS not from Acme DNS
Could you please help me?

Best Regards
