Cannot add sharepoint 2016 app to my site collection

[kristofdc]

Hi all,

I uploaded my Sharepoint hosted add-in (based on VS2017 sharepoint-hosted add-in template) to my AppCatalog in Sharepoint 2016.

Adding the app to a developer site collection is no problem, but when I try to add the app to a non-developer site collection (Site Content > Add an app > From Your Organization), the app is not visible ("there is nothing here yet") on _layouts/15/addanapp.aspx

I already checked the permissions: my user that want to add the app is site collection administrator on both site collections (appstore + the site collection where my app will be added)

Any idea why my Sharepoint 2016 app is not visible on page 'addanapp.aspx' while the app is deployed in the AppCatalog.

Can you confirm your environment is configure to Add-Ins deployment (I guess so, but just to confirm)?

Hi,

Problem was solved by following a Pluralsight course (https://app.pluralsight.com/library/courses/configuring-sharepoint-2013-for-apps) and creating a new web application and configuring the appcatalog again (including DNS config)

thx for reply !
