Create virtual host for Laravel in xampp using port 8003

I am trying to create a virtual host for my project in Laravel using Xampp.

• Already add 127.0.0.1 proyecto.com in the file hosts of C:\Windows\System32\drivers\etc
• Change the value 80 to 8003 in the file httpd.conf of C:\xampp\apache\conf
• Add the following:

<VirtualHost *:80> DocumentRoot "C:/xampp/htdocs/proyecto/public" ServerName proyecto.com </VirtualHost>

in the file httpd-vhosts.conf of C:\xampp\apache\conf\extra

When I leave everything with port 80 if I can access the project with proyecto.com , but when I change everything for 8003 does not load, it says it can not be accessed.
