epowers

My domain is www.epowerslanka.com It is hosted in Heliohost, the problem is when I try to brows the web via my IE or Firefox it says "server not found". So I tried to brows it through a proxy(www.bebooxy.com) Then I can see my site well ! What is the wrong with this problem? I am not using any domain forwarding or IP deny system. Anyone can help me, I would be greatfull for you ! Please see my site also !
