The page that you see there is a parking page from a domain registration company or a similar site. It is unlikely that this page is on your server (if you havent uploaded it yourself).
There are 2 likely options:
1) The IP address of your domain does not point to the server yet. You can test this on your workstation by using the ping command:
ping
www.yourdomain.com
ping should then shwo the IP address of your server. If you dont see the IP of your server, then you have to correct the DNS Records of your domain.
2) the other option is that you might have misspelled the domain name.
