ViewsInvalid HTTP_HOST header: '0.0.0.0:8000'. You may need to add '0.0.0.0' to ALLOWED_HOSTS
Django does not seem to find my host 0.0.0.0
I have already added "0.0.0.0" to my ALLOWED_HOSTS. In fact, if I print(ALLOWED_HOSTS) I get
['localhost', '127.0.0.1', '0.0.0.0', '[::1]']. I am working in docker. Is there anything I am overlooking?
.env.dev
DEBUG=1
SECRET_KEY=foo
DJANGO_ALLOWED_HOSTS=localhost 127.0.0.1 0.0.0.0 [::1]
SQL_ENGINE=django.db.backends.postgresql
SQL_DATABASE=xxxx
SQL_USER=xxxx
SQL_PASSWORD=xxxx
SQL_HOST=db
SQL_PORT=5432
DATABASE=postgres
env_settings.py
import os
# SECURITY WARNING: keep the secret key used in production secret!
SECRET_KEY = os.environ.get("SECRET_KEY")
# SECURITY WARNING: don't run with debug turned on in production!
# DEBUG = True
DEBUG = int(os.environ.get("DEBUG", default=0))
ALLOWED_HOSTS = os.environ.get("DJANGO_ALLOWED_HOSTS").split(" ")
# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
settings.py
from core.env_settings import *
print(ALLOWED_HOSTS)
"""
print(ALLOWED_HOSTS) returns ['localhost', '127.0.0.1', '0.0.0.0', '[::1]']
"""
NB: I have carefully reviewed all similar questions posted here and there's none with this specific problem.

You have to find your device ip address from where you are running the django app.
How to find the local ip address
To use django on local network Run command python manage.py runserver 0.0.0.0:8000
To run on other device connected to same local network you have to type ip address of your server device from where you are running django app.
192.168.1.1:8000/ # this is just dummy example.
Its should work as far both devices are connected to same network. And firewall is allowed.

I just added the ip in ALLOWED_HOSTS property in the file <your_app_path>/settings.py.
e.g.
...
ALLOWED_HOSTS = ['0.0.0.0']
...
And it worked fine.

ALLOWED_HOSTS = os.environ.get('DJANGO_ALLOWED_HOSTS', '*').split()
I'm just added split() because without split() it just localhost 127.0.0.1 0.0.0.0 [::1] for django need the list.

in settings.py,
change
ALLOWED_HOSTS = ['*']
this work for me,
*represent the all the ports can have access to the site

Take a look at settings.py and fill the ALLOWED_HOSTS as follows. For local host:
ALLOWED_HOSTS = ["0.0.0.0"]
OR you can do
ALLOWED_HOSTS = ["*"]
