URL's missing

[majost-colombia]

Hi, I'm on a very strange issue, when I try access to http://mydomain.com/lightsaml/demosp I get an "404 Route not found", I already import the routing file from the bundle and cleared the cache. The /lightsaml/login_check route neither work. Instead, /lightsaml/metadata.xml and /lightsaml/discovery works fine, I follow all instructions from getting started guide.

The configuration is made in a fresh install of Symfony 3.4. Thanks in advance.
