I was facing the same issue and after setting the maxAge attribute everything started working ok!

public WebMvcConfigurer CORSConfigurer() {
    return new WebMvcConfigurer() {
        @Override
        public void addCorsMappings(CorsRegistry registry) {
            registry.addMapping("/**")
                    .allowedOrigins("*")
                    .allowedHeaders("*")
                    .allowedMethods("GET", "POST", "PUT", "DELETE", "HEAD")
                    .maxAge(-1)   // add maxAge
                    .allowCredentials(false);
        }
    };
}

if you check the CrossOrigin annotation it has a default value assigned to that attribute

/**
 * 
By default this is set to {@code 1800} seconds (30 minutes).
 */
long maxAge() default -1;
