Redirect to HTTPS fails Spring Security - spring

Question

I got the following setup for my security:
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers("/admin/**", "/registration/**").access("hasRole('ROLE_USER') or hasRole('ROLE_ADMIN')")
.anyRequest().permitAll()
.and()
.requiresChannel().anyRequest().requiresSecure()
.and()
.exceptionHandling().accessDeniedPage("/denied")
.and()
.formLogin()
.loginPage("/login")
.failureUrl("/error-login");
}
Now problem is when i deploy it on production server when i try open demo.com or http://demo.com or combination of such, i get too many redirects and it fails.
On Chrome: ERR_TOO_MANY_REDIRECTS
On Firefox: The page isn't redirecting properly
In other words it redirects until it fails.
Any advice on what could be wrong here or what i could do to figure out the problem?
EDIT 1:
Controller request
#Controller
public class BaseController {
#RequestMapping(value = {"/", "/index"})
public String home() {
return "index";
}
}
Log: No entries (other than standard bootup sequence)

You have to specify port mapping in your WebSecurityConfigurer with the corresponding HTTP and HTTPS ports of your application:
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers("/admin/**", "/registration/**").access("hasRole('ROLE_USER') or hasRole('ROLE_ADMIN')")
.anyRequest().permitAll()
.and()
.requiresChannel().anyRequest().requiresSecure()
.and()
.portMapper()
.http(8080).mapsTo(8443);
.and()
.exceptionHandling().accessDeniedPage("/denied")
.and()
.formLogin()
.loginPage("/login")
.failureUrl("/error-login");
}
http.portMapper().http(8080).mapsTo(8443) maps your HTTP 8080 port to HTTPS 8443 port to correctly perform the redirect.
