Flush DNS

Please, have in mind that domain propagation can take up to 48h. In case it doesn't load for you even after that time, you must flush your DNS - https://www.whatsmydns.net/flush-dns.html
The easiest way to check do you need to flush your DNS is to try to open your site on the device you didn't use earlier to load your site (e.g. a mobile device), or ask some of your friends if the site loads for them.

After you do all steps from this tutorial and flush your DNS, the site will start to load for your device.
