Mailhog is not working in Laravel 8.x + Sail

I'm using Sail with Laravel 8.x
I set it up and it's working perfectly.
However, as said here in the Doc, I'm supposed to be able to access the MailHog web interface at: http://localhost:8025 since I configured my .env like this:

MAIL_HOST=mailhog
MAIL_PORT=1025
MAIL_ENCRYPTION=null

But http://localhost:8025 shows me This page isn’t working

Any help? Please!

This my docker-compose.yml file
