Hello guys. After a certain time I returned an error and did not complete the installation.

You already have a webserver running on port 80 on your host machine.

You’ll either need to stop it (and disable it), or use the custom ports file (which is explained in the following section in the manual).

Before doing so, you’ll need to run docker-compose down
