Why is Django sending me Invalid HTTP_HOST header with my server IP?

Question

So Django is sending me mail with this info:

[Django] ERROR: Invalid HTTP_HOST header: '<my server IP here>'.You may need to add u'<my server IP here>' to ALLOWED_HOSTS.

No stack trace available

Request repr() unavailable.

The problem is... You can't access my website with the server IP because I only allowing domain that already is in the ALLOWED_HOST setting.

So... What should I do?

Edit: I am using Nginx -> Gunicorn. This error only happens sometimes, like 1-2 times per week.

Probably because you didn't set the header before proxying to django, please add your virtual host config file and describe your server structure if it has anything special. — Mohammad AbuShady, Jan 21 '14 at 17:55
This is not happening very often, so it's hard to find the reason for the error message. Anywat, I am using Nginx -> Gunicorn -> Django — Spindel, Jan 21 '14 at 18:05

Found the reason.

It was when someone tried to access the server via IP over HTTPS, as in https:// (and the server-ip)

The solution is to disable that option.

Solution for Nginx:

server {
    listen      80;
    listen      443 ssl;
    ssl_certificate    /etc/ssl/example.crt;
    ssl_certificate_key    /etc/ssl/example.key;
    return      444;
}

This is happening to me to. How did you disable it? – Sunjay Varma Aug 23 '14 at 15:42
It depends on what web server you are using. I am using Nginx so I edited the nginx.conf and disabled it. – Spindel Aug 26 '14 at 06:34
