SharePoint Web Applications: Configured appcatalog and app url. No issues adding SharePoint-hosted apps or apps from the store. They all go to http://prefix-587436.CustomName-apps.ml
I am trying to add a provider-hosted app. Whether I set app's site to be on its own, created in IIS http://ProviderHostedApp, or in http://CustomName-apps.ml site, I receive an error:
DNS address could not be found
Any hints or suggestions are most welcome.
