Spring Boot Google Oauth2 all requests return a 401 Unauthorized - spring

Question

I have a very simple Spring Boot app where I want all pages to be authenticated thtough Google Oauth2. I followed the Spring Oauth2 tuotrial and looked at the code under the /simple implementation. (My application.yml file is setup for Google instead of FB)
Any request to my app returns a 401 Unauthorized response, and goes to localhost:8080/login... (The Spring security auto generated login page, which is set as the Redirect URI in Google developer console)
I have looked at all the other questions that try to answer this issue, but none have been of help.
My Application class:
#SpringBootApplication
#EnableOAuth2Sso
#RestController
public class ControlApplication extends WebSecurityConfigurerAdapter {
public static void main(String[] args) {
SpringApplication.run(ControlApplication.class, args);
}
#Override
protected void configure(HttpSecurity http) throws Exception {
http.antMatcher("/**").authorizeRequests().anyRequest().authenticated().and().formLogin().defaultSuccessUrl("/", false);
}
}
And my application.yml:
security:
oauth2:
client:
clientId: [MyClientID]
clientSecret: [MyClientSecret]
accessTokenUri: https://accounts.google.com/o/auth2/token
userAuthorizationUri: https://accounts.google.com/o/oauth2/auth?hd=xyz.com
redirectUri: http://localhost:8080
clientAuthenticationScheme: form
tokenName: oauth_token
authenticationScheme: query
scope:
- email
- profile
resource:
userInfoUri: https://www.googleapis.com/oauth2/v3/userinfo
preferTokenInfo: true

Answer 1

Solved. (Finally!) The issue appears to be wrong config for acessTokenUri in calling the Google Auth API. Working config:
accessTokenUri: https://www.googleapis.com/oauth2/v4/token
userAuthorizationUri: https://accounts.google.com/o/oauth2/v2/auth?hd=xyz.com
clientAuthenticationScheme: form
scope:
- openid
- email
- profile
resource:
userInfoUri: https://www.googleapis.com/oauth2/v3/userinfo
preferTokenInfo: true
