Google Play service error creating OAuth2.0 client

Question

I’m trying to test the features of Google Play services in an application that I have already published.

I went through the link below to do this.

https://developers.google.com/games/services/console/enabling

When I try to authorize the application, I get the message "Package name and fingerprint combination already exists."

Is there any way to remove the old combination? I do not see this combination in my developer console. Any help would be really appreciated.

I ran into the same problem, and as soon as I opened my Google API console, I already found the OAuth2 key, which I generate for testing purposes. I deleted this key, returned to the game service and tried the same procedure to link and check my game. It is working. Give it a try.
