My problem started as follow:

  1. I installed SharePoint 2013 and Visual Studio 2012.
  2. When I first try to deploy a SharePoint hosted app I got the following compilation error in visual studio

Error occurred in deployment step 'Install app for SharePoint': App Management Shared Service Proxy is not installed.

  1. So I performed these steps mentioned inside this link

Now the App will be published successfully, but if I try to access the App from SharePoint using the login local administrator or the SPManagedAccount user; a blank page will be displayed after being prompted to enter username and password multiple times.

What am I missing?

Just disable Loopback Check - solved the problem for me.

Here's some PowerShell to do this:

New-ItemProperty HKLM:\System\CurrentControlSet\Control\Lsa -Name "DisableLoopbackCheck" -value "1" -PropertyType dword


Keep in mind, that Loopback Check is essentially a security feature. Disabling it in a productive environment should only be considered if it has an impact on the normal usage and not for debugging reasons.
