Hi All,

I wonder if anyone can help me? I have configured the App environment as per the Microsoft documentation, created the app catalogue etc. I can add apps in CA they appear fine, I can also see them in site collections - when I click add in  a site collection it pops up with trust it so i click trust it and i then get the error "connect connect to windows store, please try again later"? Proxy settings are enabled in the web config, the feature is enabled in the web app and the services are started too. I can connect to the windows store on the farm servers and through the sites as well only appear when I try and trust the app. Any advice would be great, thanks in advance... 

Hi,

I understand you need to make your SharePoint 2013 available to install and configure Apps from App store.

Here is the guidence you would refer: (Quote from https://technet.microsoft.com/en-us/library/fp161232(v=office.15).aspx )

From your description, you have configured the App environment, created the app catalogue. Did you configure app authentication between these two steps? If not, please check the link below:

Hi Rebecca,

Thanks for the response, sorry for not replying sooner but I have been away -  I have looked through these and it looks like user permissions as fiddler gives me a 401 error just after i click trust it on the app, I have also spoken to one of my colleagues who can add the app whilst most can't.

Where would I need to go to change this as I am not sure?

Regards,

Hi,

Please refer to this article: https://technet.microsoft.com/en-us/library/jj655398(v=office.15).aspx

If you do not have an Office 365 subscription or if the app does not use Azure Active Directory for authentication, you must configure a server-to-server trust relationship between the SharePoint farm and the app, known as a high-trust app. A high-trust app generates its own context tokens when it requests access to a SharePoint resource. This must be done for each high-trust app that a SharePoint farm must trust. For example, if multiple apps are running on one server and if they all use different token signing certificates, you must create a separate trust with each one.

Here is an article which describes about "If you run into 401 unauthorized error when running a high-trust app" in Important troubleshooting tips & tricks part:
