SSL not working for ServerAlias through load balancer

["Rose, John B" <jbrose@xxxxxxx>]

Red Hat 7 Apache 2.4

We are using name based virtual hosts SSL configuration.

Which is working except not for one of our ServerAlias that goes thru a load balancer

Not using SSL works fine. We can access all these via the browser …

http://baseserver.sub.abc.com

http://first.sub.abc.com

http://first.abc.com

Using SSL we can go to these successfully …

https://baseserver.sub.abc.com

https://First.sub.abc.com

But not this …

https://first.abc.com

Here is our config …

Have tried these ..

<VirtualHost *.443>

      and

<VirtualHost first.sub.abc.com:443>

      and

<VirtualHost first.abc.com:443>

    ServerName baseserver.sub.abc.com

    ServerAlias first.sub.abc.com

    ServerAlias first.abc.com

    SSLEngine on

    DocumentRoot "/www/docs"

  <Directory "/www/docs">

    …

  </Directory>

  ProxyPassMatch ^/(.*\.php(/.*)?)$ fcgi://127.0.0.1:9000/www/docs/

  DirectoryIndex index.php index.html

SSL Certificate stuff …

</VirtualHost>

Any suggestions why the Load Balanced  SSL ServerAlias. https://first.abc.com,  is not working?

Thanks
