Sharepoint App Store Issue - Sorry, we can't seem to connect to the SharePoint Store. Try again in a bit.

Question

I have just setup a SharePoint 2013 server and attempted to enable the App store by using the following guide:
http://www.naumanahmed.com/2012/07/sharepoint-2013-app-management-service.html#!/2012/07/sharepoint-2013-app-management-service.html
Everything seemed to go ok until i attempted to download an app.
When SharePoint attempts to get to the app store i get an error saying 'Sorry, we can't seem to connect to the SharePoint Store. Try
again in a bit.'.  If i look at the logs the only error i can see relating to the App Marketplace is this:
An exception was thrown while running task 'GetOfficeMarkets'. Microsoft.SharePoint.SPException: Sorry, we can't seem to connect to the SharePoint Store. Try again in a bit.
at Microsoft.SharePoint.Marketplace.OfficeProxy.OfficeProxy.GetMarkets(String userDefaultBillingMarket, String userDefaultContentMarket, String userIP, List`1& markets, Boolean& validDefault)
at Microsoft.SharePoint.ApplicationPages.StorefrontBase.GetOfficeMarkets(HttpRequest request, List`1& markets, Boolean& validDefaults)
at Microsoft.SharePoint.ApplicationPages.StorefrontBase.TaskGetOfficeMarkets()
at Microsoft.SharePoint.ApplicationPages.StorefrontBase.TryRunTask(TryGetOutput taskMethod)
The server was using a proxy to connect to the internet, but since getting this error i have allowed it to directly access the internet on port 80 and 443.
Any Help would be greatly appreciated.

Are we able to access sharepoint store from PC
http://office.microsoft.com/en-in/store/
Use fiddler and netmon for blocked ports
Make sure your app domain works fine.
Make sure App Management Service and Microsoft SharePoint Foundation Subscription Settings Service is started on your server.
Make sure App Management Service Application and Microsoft SharePoint Foundation Subscription Settings Service Application is started.
Check the detail error message of ULS log  to determine the exact cause of the error.

 checked network, DNS, proxy, certificates, App/System Logs, ULS logs.. nothing....   then it clicked!
Dive into Central Admin->Manage Web Applications,
select the web-application and up in the Ribbon, select Manage Features
now ACTIVATE for internet access to the Store!
"Apps that require accessible internet facing endpoints"
"Allow users to acquire apps that require internet facing"
"endpoints from the SharePoint Store."
IISRESET and voila! everything works fine.
