No Apps Currently available, office for apps using Azure Web Site and office 365

I am trying to deploy and use an app for office. I created a simple Apps for Office project in Visual Studio 2013 and I deployed the web project to an Azure Web Site.

I changed the SourceLocation of the Manifest file to point to https://myAzureWebSite/app/home/home.html and I followed this article to deploy the app project to the Apps for Office list in my App Catalog site collection which I created it in my Developer tenant in Office 365. http://ift.tt/1yJ9Eoj.

I have trusted my app catalog by going to Excel -> File -> Options -> Trust Center -> Trust Center Settings -> add url of the app catalog site collection and clicked ok.

I have reopened the excel file and go to Insert -> My apps -> My Organization but it shows No Apps currently available
