com.netflix.hystrix.exception.HystrixRuntimeException: ProductCommentFeign # getComments (int) истекло время ожидания и произошел сбой.] с root причиной

Question

Мой единственный вопрос: почему ProductCommentFallbackFactory.class не вызывается при превышении времени ожидания сетевого запроса? Пожалуйста, помогите мне, Спасибо, код как:

@FeignClient(value = "EurekaClientProductComment",fallbackFactory = ProductCommentFallbackFactory.class)
public interface ProductCommentFeign {
    @GetMapping("/comments/product/{id}")
    public List<Comment> getComments(@PathVariable("id") int id);
}

ProductCommentFallbackFactory.class следующим образом:

@Service
public class ProductCommentFallbackFactory implements FallbackFactory<ProductCommentFeign> {
    private static List<Comment> staticComment=new ArrayList<>();
    private Logger logger= LoggerFactory.getLogger(ProductCommentRequestFallback.class);

    static {
        staticComment.add(new Comment(1,"request failed",23));
    }
    @Override
    public ProductCommentFeign create(Throwable throwable) {
        return new ProductCommentFeign() {
            @Override
            public List<Comment> getComments(int id) {
                return staticComment;
            }
        };
    }
}

global config:

feign.hystrix.enabled=true
feign.httpclient.enabled=false
feign.okhttp.enabled=true
feign.client.config.default.connect-timeout=10000
feign.client.config.default.read-timeout=10000

ошибка консоли:
