Site Address (URL)

Hi,

I am hosting my own Ubuntu server.
The installation went fine and everything seem to work, but I just can’t seem to fix the following:

under Settings -> General
WordPress Address (URL): https://84.107.47.206
Site Address (URL) : https://84.107.47.206

I want to change the Site Address to https://www.skware.nl
It’s a domain it registered at mijndomein.nl
I configured the domain so that It redirects to 84.107.47.206.

I want to set the Site Adress to skware.nl for SEO improvements.
Whenever i set the Site Adress to skware.nl, and skware.nl is visited with any browser, only the main page loads.

I hope someone can point me out on whatever this problem may be.
