spring-boot returns 404 on html

Question

I can't explain why my spring-boot app won't render my html pages anymore. I am running Spring-Boot 1.1.7 and have my index.html under src/main/resources/templates/. I am using AutoConfiguration, but when I try to navigate to my home page, nothing is rendered and I get the following in my logs:

Here is my configuration:

@ComponentScan
@EnableAutoConfiguration
@EnableGlobalMethodSecurity(securedEnabled = true)
public class MyApplication {

    public static void main(String[] args) {
        ApplicationContext edm = SpringApplication.run( MyApplication.class, args );
    }
}

and I do have Spring-Security configured as:

@Configuration
@EnableWebMvcSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private CustomUserDetailsService customUserDetailsService;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests()
                .antMatchers("/").permitAll()
                .antMatchers("/menu").permitAll()
                .antMatchers("/error").permitAll()
                .antMatchers("/resources/**").permitAll()
                .antMatchers("/css/**").permitAll()
                .antMatchers("/js/**").permitAll()
                .antMatchers("/fonts/**").permitAll()
                .antMatchers("/libs/**").permitAll();
}

As I understand it, Spring-Boot MVC will give me the index.html, view resolvers, converters, etc. I was originally using a WebMvcConfigurerAdapter but I took that out as a part of trying to solve this. I don't think I really need it as I believe springmvc will just render each html that I link to provided its in the /template directory. Except that it isn't finding them.
