Que tal, pues luego de varias pruebas y el apoyo directo de un communiter, hemos "topado" en el mismo problema, jajaja, que el servidor no navega y por ende, ESE es el pricnipal problema. Consulte con mi examinador y en efecto, ese es el reto a solucionar
Dear Jose,
Thank you very much for your email.
You are correct that the server does not connect to the internet. For
the test, it is your job to log in over VNC and fix the configuration
of the server so that it does connect to the internet so that the
website is visible on the public IP.
Please let us know how you get on and don't hesitate to contact us
with any other questions.
