Laravel Project with Docker

I follow this tutorial:

• https://www.howtoforge.com/tutorial/dockerizing-laravel-with-nginx-mysql-and-docker-compose/

When I run the command "docker-compose up -d" and open in the browser I get this error message "Unable to connect". I think the problem is with configurations off nginx (laravel.conf) I try apply some tests only to HTTP and i can't put it work. Thanks in advance
