@integracao, not sure if this was a temporary issue at the time you'd attempted login. When I use your URL (as seen in the screenshot https://voxsoluestecnolgica.saas.appdynamics.com/controller) from a new Chrome session, I can successfully see the login screen. Ofcourse without knowing your credentials, I'm unable to proceed further. But I see no 404s. Wanna try again and report back please
