Cannot access Django project homepage (Docker)

I'm building an app with Django, but although my app runs fine (at least, it's what CLI tells me) I can´t access it via browser.

The docker-compose build and up works just fine, I get this output:

 matt $ docker-compose run app sh -c "python manage.py runserver"             [+] Creating 2/2✔ Network nexus_default  Created                                                                         0.0s ✔ Container nexus-db-1   Created                                                                         0.1s [+] Running 1/1✔ Container nexus-db-1  Started                                                                          0.2s Watching for file changes with StatReloaderPerforming system checks...System check identified no issues (0 silenced).March 08, 2024 - 23:21:49Django version 5.0.3, using settings 'app.settings'Starting development server at http://127.0.0.1:8000/Quit the server with CONTROL-C.

But I can't access it through my browser (Screenshot attached)

My configs are below

Also, this is my docker ps
