Unknown error when Google authentication

[DayDve]

I created OAuth like this Credentials OAuth consent screen different to installation doc. However, when trying to authenticate using Oauth, I get an error:

Sign in with Google Something went wrong Sorry, something went wrong there. Try again.

With the following url: "https://accounts.google.com/info/unknownerror" And with a button "Next"

When i pressing "next", i redirecting to page with 400 error:

400. That’s an error. The server cannot process the request because it is malformed. It should not be retried. That’s all we know.

what am i doing wrong?
