HTTP ERROR 403 ao acessar swagger-ui.html

Já tentei ver se eu digitei algo de errado no SecurityConfigurations mas não vejo nada de errado.

Eu não consigo acessar a página.

@EnableWebSecurity
@Configuration
public class SecurityConfigurations extends WebSecurityConfigurerAdapter {

    @Autowired
    private AutenticacaoService autenticacaoService;

    @Autowired
    private TokenService tokenService;

    @Autowired

    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        //Pegando a service que tem a logica de autenticacao.
        auth.userDetailsService(autenticacaoService).passwordEncoder(new BCryptPasswordEncoder());
