invalid_client in google oauth2

Question

I try to make a web page for youtube video upload, therefore I try to get the client id from google api console, and in the api console it shows something like this:

Client ID: 533832195920.apps.googleusercontent.com
Redirect URIs: http://bobyouku.ap01.aws.af.cm/testyoutube.php
https://developers.google.com/oauthplayground

However when I try to test my account using the following URL:

https://accounts.google.com/o/oauth2/auth?client_id=533832195920.apps.googleusercontent.com&redirect_uri=http%3A%2F%2Fbobyouku.ap01.aws.af.cm%2Ftestyoutube.php&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fyoutube&response_type=code&access_type=offline

It gives out the result of invalid_client. Even when I try it on oauth2 playground, same fail occurs

So anyone knows what's happen?

Set/change your product name, I had this issue until I created a product name as same as project name.

The product name can be set in the Consent screen section of the Google Developers Console for your project. Look under APIs & auth in the left navigation and select Consent screen. You need also to set your email address in the box above the product name.
