Update #1
Everything works fine from Chrome Incognito mode !

更新#1所有工作正常，从Chrome隐身模式!

Update #2 (Solution)
Seems like it was cookie issue, I cleared all cookies from my browser and now its working fine!!
Partly it could also be SECURE_PROXY_SSL_HEADER issue as it was wrong in my settings.py

更新#2(解决方案)似乎是cookie问题，我清除了浏览器中的所有cookie，现在它工作得很好!在某种程度上，它也可能是SECURE_PROXY_SSL_HEADER问题，因为它在我的settings.py中是错误的

It seems you have made a mistake while naming http-header. You have to ensure that the name of the X-Forwarded-Proto header is correct in both: nginx configuration and Django's settings.py.

似乎您在命名http-header时犯了一个错误。您必须确保x -转发- proto头部的名称在nginx配置和Django的设置中都是正确的。

So you should modify your settings.py file by replacing the line:

所以你应该修改你的设置。py文件替换行:

SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTOCOL', 'https')

with this one:

这一个:

SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https')

Or you can add to nginx configuration file the line below:

或者您可以添加到nginx配置文件如下:

    proxy_set_header X-Forwarded-Protocol https;

I was getting the same error in a comparable setup without Cloudflare: Nginx -> Gunicorn -> Django.

在没有Cloudflare的类似设置中，我得到了同样的错误:Nginx -> Gunicorn -> Django。

I fix it by changing this Nginx setting:
proxy_set_header X-Forwarded-Proto https;
To this:
proxy_set_header X-Forwarded-Proto $scheme;

我通过更改Nginx设置来修复它:proxy_set_header x - forward - proto https;为此:proxy_set_header x - forward - proto $scheme;

So that the scheme is not hard-coded, but instead derived from the request.

这样方案就不是硬编码的，而是从请求派生出来的。
