Apps wont load on WiFi network

[Jahan Uddn]

So I have this problem apps won't load when I open them on my WiFi for example:

If I load eBay it would say "Were sorry, but the item can't be displayed" happens for ALL items. Same thing happens in UKHOTDEALS app. But when I switch off WiFi and use it on 3G network loads fine?

I thought it would be my WiFi but everything else works and my internet is fine.
