With that small amount of information, its totally impossible to have any idea. But why are you running a VPS with Windows and Xampp? The worst infrastructure i can imagine. Either run Linux with preinstalled webserver or simply run a full featured webhost.
Now you have to admin your VPS, your Windows, your Xampp, your Mysql and if anything does go wrong (like now), you dont know which component is responsible. Windows is known for having such TCPIP problems, especially with some CMS like Wordpress, Joomla etc. The internet is full of requests because of slow installations.
P.S.: The subdomain forum.dreamaion.net loads normal, so it is neither a Xampp problem, nor any infrastructure problem, it looks like a problem with the main page or script.
