tantan Hello, I’m trying to change port 80 and 443 in the mailcow.conf configuration but it doesn’t work, I have errors and I have opened the ports on my firewall, has anyone done this yet? thank you for help.
heavygale To apply your changes, run docker compose down followed by docker compose up -d. Did you apply the changes this way? What errors are occurring?
D4niel The Let’s Encrypt HTTP validation for the certificate only works over Port 80 afaik. https://letsencrypt.org/docs/challenge-types/#http-01-challenge
