WordPress As A Symfony (Symfony3) Subdirectory - php

Question

I am running a Symfony app on DigitalOcean. I have setup the entire site and created VirtualHosts. I need to run WordPress as a subdirectory (/blog). From what I know Symfony tends to ignore subdirectories in /web so I created /web/blog and installed WordPress in it.
<VirtualHost *:80>
DocumentRoot /var/www/html/site.com/web
<Directory /var/www/html/site.com/web>
AllowOverride None
Order Allow,Deny
Allow from All
<IfModule mod_rewrite.c>
Options -MultiViews
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ app.php [QSA,L]
</IfModule>
</Directory>
ErrorLog /var/log/apache2/symfony_error.log
CustomLog /var/log/apache2/symfony_access.log combined
</VirtualHost>
On localhost installations without VirtualHost this runs perfectly.
But on the live server, lets say at 21.21.21.21 I have Symfony running and 21.21.21.21/blog should open blog but it doesn't, instead goes to a Symfony 404. Whereas 21.21.21.21/blog/index.php runs the blog (WordPress).
The WordPress .htaccess which lives in /web/blog is as follows:
Options -Indexes
DirectoryIndex index.php
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /blog/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /blog/index.php [L]
</IfModule>
# END WordPress
I have tried tinkering with this with some answers on the web, nothing changes.

Update your vhost so that you exclude your /blog directory from symphony rules. And you will also need to change to AllowOverride All since you are using .htaccess in /blog.
<VirtualHost *:80>
DocumentRoot /var/www/html/site.com/web
<Directory /var/www/html/site.com/web>
AllowOverride All
Order Allow,Deny
Allow from All
<IfModule mod_rewrite.c>
Options -MultiViews
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !^/blog(/.+)? [NC]
RewriteRule ^(.*)$ app.php [QSA,L]
</IfModule>
</Directory>
ErrorLog /var/log/apache2/symfony_error.log
CustomLog /var/log/apache2/symfony_access.log combined
</VirtualHost>
Be sure to restart apache after changes.
WordPress .htaccess Changes:
Options -Indexes
DirectoryIndex index.php
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /blog/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /blog/index.php [L]
</IfModule>
# END WordPress
