php - Setting up subdomain - AWS & Laravel

I'm slowly migrating my website into the artisan era using Laravel.

I have it setup on AWS on a vanilla Amazon linux.

Currently I have;

www.example.co.uk

blog.example.co.uk

careers.example.co.uk

These are all on the same server and the subdomains have been achieved using htaccess to redirect to \blog and \careers folders in my root with DNS being handled by Route 53

Now in moving to laravel it only considers the public folder (htaccess use no longer required apart from the default one it comes with) so I have my DocumentRoot as /var/www/example/public. Everything works great! Setup a bunch of routes for my main site and still smooth sailing.

Now moving to the subdomains, I have the below in my hhtpd.conf

<VirtualHost *:80>
ServerName blog.example.co.uk
ServerAdmin [email protected]
DocumentRoot /var/www/example/public
<Directory /var/www/example/public>
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
allow from all
</Directory>
ErrorLog /var/log/blog.example.co.uk.error.log
LogLevel warn
CustomLog /var/log/blog.example.co.uk.access.log combined
</VirtualHost>

As you can see I'm pointing the subdomain to the same public folder since Laravel should be able to see that blog.example.co.uk was requested and perform its duties to route correctly.

I have the below routes for the subdomain

Route::group(['domain' => 'blog.example.co.uk'], function () {
Route::get('/', '[email protected]')->name('blog-home');
Route::get('review', '[email protected]')->name('blog-review');
Route::get('author/{id}', '[email protected]')->name('blog-author')->middleware('blogGuard');
Route::get('category/{id}', '[email protected]')->name('blog-category')->middleware('blogGuard');
Route::get('post/{id}', '[email protected]')->name('blog-post')->middleware('blogGuard');
Route::get('press', '[email protected]')->name('blog-press');
Route::get('about', '[email protected]')->name('blog-about');
});

Unfortunately, going to blog.example.co.uk still assumes that I requested www.example.co.uk and routes using the logic for the main site. So blog.example points to www.example.

I have also used '{blog}.example.co.uk'

What am I doing wrong please

Cheers!
