Central runs on ports 80/443 and that’s conflicting with your other services.

If you'd like to run it on other ports, you'll need to change the ports you'd like to use in `.env` (and not in `docker-compose.yml`). And once you change those ports, you'll need to change your SSL\_TYPE to something besides `letsencrypt` because Let's Encrypt requires port 80.

If you have your own cert, use the `customssl` type and follow the instructions at [https://docs.getodk.org/central-install-digital-ocean/#using-a-custom-ssl-certificate](https://docs.getodk.org/central-install-digital-ocean/#using-a-custom-ssl-certificate). If you don't have your own cert, you'll need to use the `upstream` type and set up an SSL-enabled upstream provider (e.g., a load balancer or a reverse proxy) that routes traffic to ports that Central is running on.
