My apache2 VirtualHost keep showing "It's working" instead of my site - apache

Question

I'm doing a project for school where I have to host 2 pages on a web server. I chose to do a VirtualHost using Apache2 but when it keeps showing me a "It works" page. The page is located here.
We are using a DNS server but the probleme seems to not be coming from this one.
Here is one of the .conf file :
<VirtualHost *:80>
ServerAdmin jongen.philemon#wt5.ephec-ti.be
ServerName wt5.ephec-ti.be
ServerAlias www.wt5.ephec-ti.be
DocumentRoot /var/www/monsite
<Directory /><br>
Options FollowSymLinks
AllowOverride None
</Directory>
<Directory /var/www/monsite>
Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
allow from all
</Directory>
</VirtualHost>
I also changed the apache2.conf like this:
<VirtualHost *:80>
ServerAdmin jongen.philemon#wt5.ephec-ti.be
DocumentRoot /var/www/site
<Directory /var/www/site/>
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order deny,allow
Allow from all
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
You can also check our wiki on the GitHub to see all the steps I followed.
Thank's

I got to fix it by re-doing it using a Dockerfile. I uptated the files and the wiki on my github if you have the same issue !
