I have created a Google project some time ago. The application can be found in appengine.google.com (and I can run it like this: [my-app-id].appspot.com) But I can not find it in https://console.developers.google.com/project I even tried to access it by typing the URL like this: https://console.developers.google.com/project/apps~[my-app-id] which just gives "ERROR The project you requested is unavailable" I have not deleted the project.
How can I access the console pages. The problem is that I can not access the project's permissions (OAuth keys) without the console.
Any advice for this?
I've hit this a couple of times before remembering the solution which for me was to enable the "Google Play Android Developer API" in the Google API Console. Via Library > Mobile APIs > Google Play Android Developer API and you should see an Enable button at the top of the page.
Going back and refreshing the Google Play <strong>Developer</strong> Console now shows the API Console Project for linking.<hr>
That project was so called legacy project, which needed to be "updated" in the Application Settings https://developers.google.com/appengine/kb/general#cloudintegration
