The app installs and appears however from Project Center, (with a number of custom fields created), the app results in a ‘This page can not be displayed’ message and a url – •Make sure the web address https://apps-bc582a4d057018.lexel.co.nz is correct
Not sure where it is failing. Any ideas please as the idea of the app is very attractive.
Please try and clear the cache in your browser or try from another browser / machine. This can happen when the SharePoint ribbon menu is cached by your browser and the url to the newly deployed app was not updated yet.
Otherwise if this is your first app install, please check your server farm configurations, perhaps by ensuring that other apps work, if not then there may be a configuration issue with DNS in your SharePoint App Management service.
