Deploying to LAN

When deploying my Dash app by either using

python run.py

or

gunicorn index:app.server -b 0.0.0.0:8050

with run.py:

import dash
import flask
server = flask.Flask(__name__)
app = dash.Dash(__name__,  server=server)
app.layout = ...

if __name__ == '__main__':
    app.run_server(debug=True, host='0.0.0.0')

and index.py:

from run import app
server = app.server

I can reach the app on 0.0.0.0:8050 on the machine I’m running it but on no other device in the same LAN like it is supposed to do. Anyone knows where I can start looking?

dumb me, you have to enter the other machines IP:PORT instead of 0.0.0.0:PORT
