I currently own a new server that does not appear on your website:

198.27.83.79:27145

You are correct. It does not.

This is why we have a Guides and FAQs section.
(also linked in my posting 'signature' below)

If you go to this page;
https://www.gametracker.com/servers/

You will see the option to add your server.
After adding your server, you will want to visit the FAQs section to learn how to claim the server page.
