Deploying to LAN

When deploying my Dash app by either using



gunicorn index:app.server -b


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='')


from run import app
server = app.server

I can reach the app on 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
