Hi,
today i was install mailcow on DEBIAN buster.
I have normal install, event don’t touched mallow.conf.
i read about trouble with ACME, example mailcow/mailcow-dockerized2498 and like andryyy say try:
sudo docker-compose exec acme-mailcow curl -4 http://${MAILCOW_HOSTNAME}/.well-known/acme-challenge/1 –write-out %{http_code}
and get answer: curl: (6) Could not resolve host: .well-known
Something wrong, check system var: echo ${MAILCOW_HOSTNAME} and is empty!
But if i ask about IP, no DNS name: sudo docker-compose exec acme-mailcow curl -4 http://xxx.xxx.xxx.xxx/.well-known/acme-challenge/1 –write-out %{http_code}
and get answer: Empty reply from server
I don’t undestand what’s wrong…
