Django runserver returns ERR_CONNECTION_RESET on Windows 11 (no errors in terminal)

I’m learning Django and trying to run my project locally on Windows 11.
When I start the server, it runs without any errors, but when I try to open it in my browser (127.0.0.1:8000 or 127.0.0.1:8001), I get this message:

Hmmm… can’t reach this page  
ERR_CONNECTION_RESET

What I’ve Tried

• Running python manage.py runserver 0.0.0.0:8001

• Running from both PowerShell and Command Prompt

• Confirmed I’m using a virtual environment (venv) inside my project folder

• Checked that my firewall allows Python

• Reinstalled Django and Python

• Verified no errors show in the terminal

Terminal output:

Watching for file changes with StatReloader
Performing system checks...

System check identified no issues (0 silenced).
Django version 5.2.5, using settings 'StudentERP.settings'
Starting development server at http://0.0.0.0:8001/
Quit the server with CTRL-BREAK.

WARNING: This is a development server. Do not use it in a production setting.

What I Expected

I expected to see Django’s default “Congratulations!” page at http://127.0.0.1:8001/.

My Setup

• Windows 11 Home, Version 23H2 (Build 22631)

• Python 3.11.9 (64-bit) installed from python.org

• Django 5.2.5

• Running inside VS Code PowerShell terminal

• Personal laptop (not managed by any organization)

Question

Why am I getting ERR_CONNECTION_RESET even though Django runs without errors?
Is there something wrong with my local setup or the port binding?
