How to access the local Django webserver from outside world

You have to run the development server such that it listens on the interface to your network.

E.g.

python manage.py runserver 0.0.0.0:8000

listens on every interface on port 8000.

It doesn't matter whether you access the webserver with the IP or the hostname. I guess you are still in your own LAN.
If you really want to access the server from outside, you also have to configure your router to forward port e.g. 8000 to your server.

Check your firewall on your server whether incoming connections to the port in use are allowed!

Assuming you can access your Apache server from the outside successfully, you can also try this:

• Stop the Apache server, so that port 80 is free.
• Start the development server with sudo python manage.py runserver 0.0.0.0:80

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...

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 ;)

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 = ['*']

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

install ngrok in terminal

sudo apt-get install -y ngrok-client

after that run:

ngrok http 8000
or 
ngrok http example.com:9000
