Why doesn't the site open locally?

Question

Apache HTTP Server

Installed a clean Ubuntu 16.04, installed LAMP, added my.domain.local to the hosts file 127.0.0.1
Added my.domain.loca.conf to apache2

<VirtualHost *:80>
        ServerName  my.domain.local
        DocumentRoot /var/www/my/backend/web
        <Directory /var/www/my/backend/web>
            RewriteEngine on
              RewriteCond %{REQUEST_FILENAME} !-f
              RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . index.php
            Options Indexes FollowSymLinks MultiViews
   AllowOverride None
   Order allow,deny
   allow from all
        </Directory>
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

In FireFox, the site works, but in chrome, at first there was a certificate error, I turned it on in apache ssl, to sense 0.
Constantly ERR_CONNECTION_REFUSED Unable to access the site
Why is that?
