2 websites hosted on same domain, 1 needs to look like a subfolder ( /blog)

Question

I bought a VPS for my new project running apache.
On it I have 2 websites on the same domain.
The first one is Ruby on Rails /var/www/html
The second one is Wordpress /var/www/blog

I want Wordpress to act like a subdirectory of ruby ( /blog).
Ruby on Rails website works, but if i go to /blog it just says that the page im looking is not available(with RoR 404 template)

Conf for RoR:

<VirtualHost *:443>
        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/html/public
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
        SSLEngine on
        SSLCertificateFile /etc/apache2/certificate/apache-certificate.crt
        SSLCertificateKeyFile /etc/apache2/certificate/apache.key
  
</VirtualHost>

Conf for Wordpress:

<VirtualHost *:443>
        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/blog
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
        SSLEngine on
        SSLCertificateFile /etc/apache2/certificate/apache-certificate.crt
        SSLCertificateKeyFile /etc/apache2/certificate/apache.key
        Alias /blog /var/www/blog
</VirtualHost>

Maybe the solution is a htacces file in /var/www. Can you pleasep point me? Thank you !

On it I have 2 websites on the same domain.

Well, you actually have 1 website (1 domain). It's just that you have WordPress in a subdirectory of that 1 website. Consequently, you should only have 1 <VirtualHost> container, not 2 - which is where you would seem to be going wrong here.

The second <VirtualHost> is not being used and should be removed.

You need to move the Alias /blog /var/www/blog directive into the first <VirtualHost> container and allow access to this directory by including the following inside the vHost container:

# WordPress
<Directory /var/www/blog>
    # Permit access to this area
    Require all granted

    # Allow per-directory overrides if want to use WP htaccess file
    AllowOverride All
</Directory>

I assume you must already have something similar for /var/www/html/public?

You should really include a ServerName directive inside this vHost container, otherwise, this is just acting as the "default" by being defined first. For example:

# Declare the hostname that this vHost defines
ServerName example.com

And then define a "default" vHost container before this that catches non-canonical requests.
