My Bitnami Django website shows the Bitnami homepage instead of mine. How to change it?

I deployed a website on AWS LIGHTSAIL. I assigned an static IP to that instance and when I enter to it, it shows me the Bitnami homepage.

When I run the virtual env in the Django project (python manage.py runserver 0.0.0.0:8000) I have to put the :8000 on my static IP for my website to shows up.

What I'm doing wrong? How do I make my website appears on the default port? Thanks!
