Invalid HTTP_HOST header: 'subdomain.domain.com'. You may need to add 'subdomain.domain.com' to ALLOWED_HOSTS

after two days From deplyoing my application and working fine, I have decided to change the name of the subdomain so i have just rename it under the path:

/etc/nginx/sites-available

and then i have did again

sudo certbot --nginx for the "https" ,

then adding this host in settings.py from my django application,

I have did sudo systemctl restart nginx to restart nginx

then:

sudo systemctl restart gunicorn

then

 python manage.py makemigrations

-->No changes detected

   python manage.py migrate

-->No changes detected

and when i go to the browser to access to my application I got this error

DisallowedHost at /

Invalid HTTP_HOST header: 'subdomain.domain.com'. You may need to add 'subdomain.domain.com' to ALLOWED_HOSTS.

, otherwise i Have added the host on "settings.py"

Help please isn't there any other step i should do when i change the host ,Thanks in advance

Solution

  • You have not showed what you have inside your Django settings.py file, but I assume you have not configured the ALLOWED_HOSTS variable as you should have. This is how it should look like:

    ALLOWED_HOSTS = [
    'subdomain.domain.com'
]

    Also, make sure to restart the HTTP server. The settings file is loaded to memory, so if you make changes to it, you need to restart the server.

    systemctl restart gunicorn
