Invalid http_host header

Question

I am trying to develop a website using Django framework and launched using DigitalOcean.com and deployed the necessary files into django-project.

I had to include static files into Django-project and After collecting static files, I tried to refresh my ip

I am including the tutorials which I have used to create the website.
https://www.pythonprogramming.net/django-web-server-publish-tutorial/

I am getting the following error :

DisallowedHost at / Invalid HTTP_HOST header: ‘198.211.99.20’. You may
need to add u’198.211.99.20′ to ALLOWED_HOSTS.

Can somebody help me to fix this ? This is my first website using Django framework.

Answer 1

The error log is straightforward. As it suggested,You need to add 198.211.99.20 to your ALLOWED_HOSTS setting.

In your project settings.py file,set ALLOWED_HOSTS like this :

ALLOWED_HOSTS = ['198.211.99.20', 'localhost', '127.0.0.1']

settings.py

ALLOWED_HOSTS = ['*'] // if you are in dev or docker

ALLOWED_HOSTS = ['62.63.141.41', 'namjoosadr.com']

and then restart your apache. in ubuntu:

/etc/init.d/apache2 restart

if no other answer work you can try modifying manage.py and add this three lines

from django.utils.regex_helper import _lazy_re_compile
import django.http.request
django.http.request.host_validation_re = _lazy_re_compile(r"[a-zA-z0-9.:]*")

to end up having something like this:

import os
import sys

from django.utils.regex_helper import _lazy_re_compile
import django.http.request    
django.http.request.host_validation_re = _lazy_re_compile(r"[a-zA-z0-9.:]*")

def main():
    """Run administrative tasks."""
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'project01.settings')
    try:
        from django.core.management import execute_from_command_line
    except ImportError as exc:
        raise ImportError(
            "Couldn't import Django. Are you sure it's installed and "
            "available on your PYTHONPATH environment variable? Did you "
            "forget to activate a virtual environment?"
        ) from exc
    execute_from_command_line(sys.argv)


if __name__ == '__main__':
    main()
