Virtual host Object not found - apache

Question

Everytime I try to access https://sub.myproject.test/ this message pops up:
Object not found!
The requested URL was not found on this server. If you entered the URL manually please check your spelling and try again.
If you think this is a server error, please contact the webmaster.
Error 404
sub.myproject.test
Apache/2.4.38 (Unix) OpenSSL/1.0.2q PHP/7.2.15 mod_perl/2.0.8-dev Perl/v5.16.3
On httpd-vhosts.conf I have:
<VirtualHost *:80>
DocumentRoot "/mnt/data/myproject/sub.myproject.com/public_html"
ServerName sub.myproject.test
ServerAlias www.sub.myproject.test
<Directory "/mnt/data/myproject/sub.myproject.com/public_html/">

</Directory>
</VirtualHost>
and on httpd-ssl.conf I have:
# catalog config
<VirtualHost *:443>
DocumentRoot "/mnt/data/myproject/sub.myproject.com/public_html"
ServerName sub.myproject.test:443

</VirtualHost>
And of course in /mnt/data/myproject path I have the sub.myproject.com folder
If you could help me fix this, it'd be very appreciated

Answer 1

Your VirtualHost is ok (except you do not need to put :443 in ServerName and ServerAlias directives), but you never tell Apache which page to display by default, when not specified in the request.
Define DirectoryIndex in each VirtualHost.
Ex: DirectoryIndex index.html
When the request is https://example.com/
,hence nothing after the domain name, Apache will display index.html, from the DocumentRoot directory.
Unrelated to your question, you should put ServerTokens Prod and ServerSignature Off in your configuration, your error message is displaying way to much information.
