[Django]-How to access the local Django webserver from outside world

I had to add this line to settings.py in order to make it work (otherwise it showed an error when accessed from another computer)

ALLOWED_HOSTS = ['*']

then ran the server with:

python manage.py runserver 0.0.0.0:9595

Also ensure that the firewall allows connections to that port

Pick one or more from:

• Your application isn’t successfully listening on the intended IP:PORT
  • Because you haven’t configured it successfully
  • Because the user doesn’t have permission to
• Your application is listening successfully on the intended IP:PORT, but clients can’t reach it because
  • The server local iptables prevents it.
  • A firewall prevents it.

So, you can check that your application is listening successfully by running lsof -i as root on the machine and look for a python entry with the corresponding port you’ve specified.

Non-root users generally cannot bind to ports < 1024.

You’ll need to look at iptables -nvL to see if there’s a rule that would prevent access to the ip:port that you are trying to bind your application to.

If there is an upstream firewall and you don’t know much about it, you’ll need to talk to your network administrators.

just do this:

python manage.py runserver 0:8000

by the above command you are actually binding it to the external IP address.
so now when you access your IP address with the port number, you will be able to access it in the browser without any problem.

just type in the following in the browser address bar:

<your ip address>:8000

eg:

192.168.1.130:8000

you may have to edit the settings.py
add the following in the settings.py in the last line:

ALLOWED_HOSTS = ['*']

hope this will help…

For AWS users.

I had to use the following steps to get there.

1) Ensure that pip and django are installed at the sudo level

• sudo apt-get install python-pip
• sudo pip install django

2) Ensure that security group in-bound rules includ http on port 80 for 0.0.0.0/0

• configured through AWS console

3) Add Public IP and DNS to ALLOWED_HOSTS

• ALLOWED_HOSTS is a list object that you can find in settings.py
• ALLOWED_HOSTS = [“75.254.65.19″,”ec2-54-528-27-21.compute-1.amazonaws.com”]

4) Launch development server with sudo on port 80

• sudo python manage.py runserver 0:80

Site now available at either of the following (no need for :80 as that is default for http):

• [Public DNS] i.e. ec2-54-528-27-21.compute-1.amazonaws.com
• [Public IP] i.e 75.254.65.19

open terminal
type : ifconfig
check results of ifconfig command
use the inet IP .. should look like this.. 192.168.1.121 or similar 192.168.x.x.

now runserver like you normally do but this time specify the inet IP
python3 manage.py runserver 192.168.x.x:8000 (replace the x with your inet)
also
on settings.py
ALLOWED_HOSTS = [‘*’]

I’m going to add this here:

1. sudo python manage.py runserver 80

2. Go to your phone or computer and enter your computers internal IP (e.g 192.168.0.12) into the browser.

At this point you should be connected to the Django server.

This should also work without sudo:

python manage.py runserver 0.0.0.0:8000

UPDATED 2020
TRY THIS WAY

python manage.py runserver yourIp:8000

ALLOWED_HOSTS = ["*"]

You need just to allow any hosts :
settings.py :

ALLOWED_HOST = ['*']

Run your server :

python3 manage.py runserver 0.0.0.0:8000

If you want to connect android app just add internet permission in AndroidManifest
It’s work for me 😉

install ngrok in terminal

sudo apt-get install -y ngrok-client

after that run:

ngrok http 8000
or 
ngrok http example.com:9000 

If you are using Docker you need to make sure ports are exposed as well
