Are you sure you know the right ip of your server?
You need find this information in your hostony's welcome email, they inform you the ip of the server where you are, and your account name and password (i think commonly your account name is the first 8 characters of your domain name)
So, if your site is "yourdomain.com", maybe your account name(username) is "yourdoma"
so if you go to
http://theserverip/~yourdoma/" it must point to the web server's "document root" of your account.
Note: When you upload your site's files thought ftp, upload them to the directory /public_html/ (/home/yourdoma/public_html/)
If nothing work, wait for the support team or contact them trought FineDesk Tickets system, at support.hostony.com, they are very effective and cooperative people.
