Django on Windows show the Django home page instead of my site

I am very beginner with python. My OS is Windows. I run Django in an environment and I am able to edit and add files and folders, etc. I can run the server with

py runserver

and I have this return

Starting development server at

So far, so good.
But if I open a browser and paste this address, I see the Django home page, not my app home page, and my urls are not recognized.
Any clues ?

Please show the directory structure of your project, along with the settings file and the content of the root file. (The root file is the file specified in your file.)

When posting code here, enclose each file between lines of three backtick - ` characters. This means you’ll have a line of ```, then your code, then another line of ```. This forces the forum software to keep your code properly formatted.

Thank you for your answer. I finally found. In the architecture, there are two dirs with the same name. I made the changes in the one which is not called by Django… stupid, but as I said, I am beginner with this language.
Thanks again.
