Alienware: Error while downloading the necessary catologs

Hi, my internet is working well but I am unable to update drivers from the Alienware Update utility. I am also unable to access Windows store as well as download drivers from the Dell support page. It keeps saying there is an issue with my internet, whereas, I am able to browse the net, and do all other things using my wifi or LAN cable... please help! Strangely, I am able to download windows updates.
