Cannot configure phpmyadmin vhost

Question

With Apache 2.4, PHP7 & Phpmyadmin on a Windows Server 2016 VM: unable to properly configure phpmyadmin to be accessible as path from site. Site is a Symfony application that throws a 404 when site/phpmyadmin is requested.

mod_alias is loaded

httpd-vhost.conf

<VirtualHost *:80>
    ServerName admin.projectmana.org
    ServerAlias projectmana.org
    DocumentRoot "c:\apache24\htdocs\projectmana\htdocs"
</VirtualHost>
<VirtualHost *:80>
    ServerAdmin [email protected]
    ServerName admin.projectmana.org
    Alias /phpmyadmin "c:/Apache24/htdocs/phpmyadmin"
    <Directory "c:/Apache24/htdocs/phpmyadmin">
    </Directory>
</VirtualHost>

Edit

Result of httpd -S (after Include conf/extra/httpd-vhosts.conf)

VirtualHost configuration:
*:80                   is a NameVirtualHost

With the help from this Ubuntu forums answer, I made the following the sole entry in httpd-vhosts.conf:

<VirtualHost *:80>
    ServerName admin.projectmana.org
    ServerAlias projectmana.org
    DocumentRoot "c:\apache24\htdocs\projectMana\htdocs"
    Alias /phpmyadmin "c:/Apache24/htdocs/phpmyadmin"
    <Directory "c:/Apache24/htdocs/phpmyadmin">
        Options Indexes FollowSymLinks MultiViews
        DirectoryIndex index.php
        AllowOverride all
        Require all granted
    </Directory>
</VirtualHost>
