To support White Labels on your Platform Edition, you need first get some settings on your server.
When creating a CNAME, if you will be redirected to another page than your Siberian, that means you have to do the following settings in your server configuration.

1) Join your Plesk panel.
2) Click on the "Server" tab.
3) In Tools & Resources tab, click on IP Addresses.
4) Click your server's IP (the IPV4 one, not the IPV6 if you have IPV6).
5) For "Default site" choose your platform, and save.
6) Enter the CNAME in your browser, and that should be ok.
2) cPanel

If you see the "Sorry" page of cPanel while entering the CNAME, do the following:
1) Connect SSH to your server.

3) Edit this file.
4) Go down and get the entry associated with your platform. It starts with <VirtualHost xx.xx.xx.xx:80>, and the ServerName is your platform's address. Copy the entry starting with <VirtualHost xx.xx.xx.xx:80> and ending with </VirtualHost> and paste it in a text editor.
5) Connect to your WHM panel.

This entry begins with <VirtualHost xx.xx.xx.xx:80> where “xx.xx.xx.xx” is the IP of your server, and it stops with </VirtualHost>. Following <VirtualHost xx.xx.xx.xx:80> you can see the ServerName which unites your default website's address.
6) Go down and see the entry related to your platform. It also starts with <VirtualHost xx.xx.xx.xx:80>, but the ServerName is your platform's address. Copy all this entry starting with <VirtualHost xx.xx.xx.xx:80> and stopping with </VirtualHost>, fix it in a text editor.
