[Python] Dash App Only Accessible on 127.0.0.1, Not on 0.0.0.0 or Local Network IP

I'm developing a multi-page Dash app using dash.pages and dash-bootstrap-components. I want to make it accessible from other devices on my local network (e.g., via 0.0.0.0:8050 or 10.233.233.158:8050), but it only opens on 127.0.0.1:8050. Accessing the app from other machines or even using the server's IP address in a browser on the same machine does not work. Also, on my Windows server, 0.0.0.0:8050 or 10.233.233.158:8050 is not opening on the browser!

Here's my app.py:

import dash
from dash import html
import dash_bootstrap_components as dbc
from utils.b2b_db import init_db

# Initialize the Dash app with Bootstrap theme
app = dash.Dash(
__name__,
use_pages=True, # Enable multi-page support
external_stylesheets=[dbc.themes.BOOTSTRAP],
suppress_callback_exceptions=True
)

# Initialize database
init_db()

# Create the navigation bar
navbar = dbc.Navbar(
dbc.Container([
dbc.NavbarBrand("ISP Analytics", href="/", className="ms-2"),
dbc.Nav([
dbc.NavLink(
[html.Div(page["name"])],
href=page["path"],
active="exact",
)
for page in dash.page_registry.values()
])
]),
color="dark",
dark=True,
className="mb-2"
)

# Layout
app.layout = html.Div([
navbar,
dash.page_container
])

if __name__ == '__main__':
app.run(host='0.0.0.0', port=8050, debug=False)


I've verified that:

• My firewall is disabled or allows traffic on port 8050.
• No errors are raised when I run the app.
  (venv) E:\ISP DASH>python app.py
  Dash is running on http://0.0.0.0:8050/
  
  Serving Flask app 'app'
  Debug mode: off

• The development server starts, but only 127.0.0.1:8050 works.

How can I make this app accessible from another machine on the same network using the local IP (like 10.233.233.158:8050)? Any help would be appreciated.

Thanks!
