A million times I checked the correctness of the ID and key.
Please take a look, maybe I filled in something wrong in the application. And then my head is already swollen from the fact that I am not able to understand what is happening.

You don't need a key to authorize via OAUTH. The problem is most likely in the authorization code, not the settings.
