apache serving the wrong ssl certificate - apache

Question

I have the following 2 sections in my httpd.conf file. I have a wildcard cert installed for *.example.biz installed at the given location. As you can see the 4 SSL directives are identical (copy and pasted) in both sections. However, when I go to example.biz I get an ssh error saying the CA certificate expired in 2015. When I go to the subdomain, I get the right certificate chain that says it expires in 2018. I apologize that I am using an example, but this is for a client that must remain confidential.
<VirtualHost *:443>
SSLEngine on
SSLCertificateFile /etc/pki/tls/certs/2017.crt
SSLCertificateKeyFile /etc/pki/tls/private/my_biz_2016.key
SSLCertificateChainFile /etc/pki/tls/certs/2017_ca.crt
<Directory /var/www/MyCompany/example.com/public/>
AllowOverride All
</Directory>
ErrorLog /var/www/logs/example.com/error.log
CustomLog /var/www/logs/example.com/access.log combined
DocumentRoot /var/www/MyCompany/example.com/public/
ServerName example.biz
</VirtualHost>
<VirtualHost *:443>
SSLEngine on
SSLCertificateFile /etc/pki/tls/certs/2017.crt
SSLCertificateKeyFile /etc/pki/tls/private/my_biz_2016.key
SSLCertificateChainFile /etc/pki/tls/certs/2017_ca.crt
<Directory /var/www/MyCompany/SubDomain/public/>
AllowOverride All
</Directory>
ErrorLog /var/www/logs/SubDomain/error.log
CustomLog /var/www/logs/SubDomain/access.log combined
DocumentRoot /var/www/MyCompany/SubDomain/public/
ServerName subdomain.example.biz
</VirtualHost>
Lastly, this is my .htaccess file if that is helpful:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
Also: I pinged both domains, and they both point to the same server and I am not using cloudflare, or anything of the like.
I also restarted apache to make sure.

Answer 1

I define all of my vhosts in a vhosts file, but in my httpd.conf file I apparently set it up with a set of defaults such as:
ServerAdmin root#localhost
ServerNAme example.biz
DocumentRoot /var/www/html # I wasn't using this folder
Once I deleted those erroneous defaults, it started working.
