问题:

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 Developer Console now shows the API Console Project for linking.

That project was so called legacy project, which needed to be "updated" in the Application Settings https://developers.google.com/appengine/kb/general#cloudintegration
