I’m trying to start a mailcow server, when docker-compose pull starts I get the following error:
ERROR: The Compose file './docker-compose.yml' is invalid because:
services.nginx-mailcow.ports contains an invalid type, it should be a number, or an object
services.nginx-mailcow.ports contains an invalid type, it should be a number, or an object
what’s the problem, what should I do?
