Add-On domain not working

[tech4u30]

Hi, i added on two domains yesterday to my account and one of them is working perfectly, but the other www.technews4u.co.uk isnt working at all. When i try going to the page it says "server not found", i set the DNS on the domain with your nameservers, have you any idea why its not working?

It seems to be working now. It can take a few days to completely propagate.
