DNS A record pinging to ip but shows error 404

I need to open the content of the ogilvyalbaniaonline.com, at test.whateveryouwant.a2hosted.com
This is done via DNS A record. If you check the images below, the DNS Configurations are all ok, and if i ping both of the sites, they both show the same IP address. But when i open test.whateveryouwant.a2hosted.com on a browser, it shows 404 error.
what am i doing wrong? advice?
