Django Settings ALLOW_HOST not updating

Hi there!

There are a few things that you could check here starting with the ALLOWED_HOSTS setting in settings.py and making sure that it is correctly set with your domain name:

ALLOWED_HOSTS = ['domain-name.com', 'www.domain-name.com']

If you’re deploying with environment variables, make sure they are properly set and imported:

import os
ALLOWED_HOSTS = os.getenv('DJANGO_ALLOWED_HOSTS', 'localhost').split(',')

Check if the environment variable DJANGO_ALLOWED_HOSTS is set in your droplet.

After that, if you use caching (e.g., with gunicorn or uwsgi), restart your Django server to apply the new settings:

sudo systemctl restart gunicorn

Or if you are using a Docker container, rebuild and restart it:

docker-compose down
docker-compose up --build -d

On another note, if DEBUG is set to True in production, it could cause unexpected behavior. Make sure to set it to False:

DEBUG = False

If this is still not working, I would suggest checking your logs for more details:

tail -f /var/log/nginx/error.log
tail -f /var/log/gunicorn/error.log

Let me know how it goes!

Heya,

If your Allowed_host has not been updated it means that your Application has not picked up the new settings. For that to work, sometimes you nead to restart your application.

If you are using a caching mechanism (Redis, Memcached), clear it to ensure stale configurations are not affecting your application.

Also you can ensure the deployed version of your settings.py or its equivalent configuration file on the DigitalOcean droplet matches your local changes. Sometimes, deployment scripts might not push updates correctly.
