CSRF verification failed. Request aborted - django

Been working on my live server all day and just got it working, admin was working fine, i cleared cookies and suddenly i got the following error, and no fixes seem to be helping me. My website does have SSL yet so its still http(dont know if this has anything to do with it?)
DEBUG = False
CSRF_TRUSTED_ORIGINS = ['http://.*', 'http://example.com', 'http://www.example.com']
# HTTPS Settings
SESSION_COOKIE_SECURE = True
CSRF_COOKIE_SECURE = False
SECURE_SSL_REDIRECT = False
# HSTS Settings
SECURE_HSTS_SECONDS = 31536000
SECURE_HSTS_PRELOAD = True
SECURE_HSTS_INCLUDE_SUBDOMAINS = True
This is the only form on my website that requires csrf_token and as you can see it already has it.

SOLVED
By adding the ip from my domain to the allowed hosts and trusted origins.

Do you have CsrfViewMiddleware in your MIDDLEWARE_CLASSES setting? Are you accessing the site non-securely (seems so) then it could not work. Try to disable CSRF_COOKIE_SECURE, CSRF_COOKIE_HTTPONLY and SESSION_COOKIE_SECURE and you will see it will work.

Django - CSRF problem after moving to production server

I moved applications to the production server and I have a problem with CSRF - Access denied (403)
CSRF verification failed. The request was aborted.
I checked in my browser and I don't have a cookie named
csrftoken
Part of my settings.py looks like this:
SECRET_KEY = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
SESSION_COOKIE_SECURE = True SESSION_COOKIE_SAMESITE = None
CSRF_COOKIE_SECURE = True CSRF_COOKIE_SAMESITE = 'Strict'
#SECURE_HSTS_SECONDS = 31536000
#SECURE_CONTENT_TYPE_NOSNIFF = True
#CSRF_COOKIE_SECURE = True
#SESSION_COOKIE_SECURE = True
#SESSION_COOKIE_SAMESITE = None
#SECURE_HSTS_PRELOAD = True
I haven't turned on HTTPS yet
Everything worked fine on the development server.
Where to find the cause and what to improve?
problem solved.
You just had to generate an SSL certificate and enable HTTPS.
This post showed me the solution Django: Forbidden (CSRF cookie not set.)
What solved it for me was to add the following to settings.py, replacing "<my_domain>" part of course.
CSRF_TRUSTED_ORIGINS = ['https://<my_domain>.com']
This code above works like magic

CSRF_COOKIE_SAMESITE equivalent for django 1.6.5

I am trying to launch my application which was written using django 1.6.5 version, in a salesforce webtab iframe. I was getting a "CSRF cookie not set" error while trying to login. I understood through the console logs that in the latest version of Chrome, only allows the cookies which are set with 'secure'=True and samesite=None. I understood that these settings can be added in the settings.py in later versions of django
SESSION_COOKIE_SAMESITE = 'None'
CSRF_COOKIE_SAMESITE = 'None'
SESSION_COOKIE_SECURE = True
CSRF_COOKIE_SECURE = True
But this does not work in django 1.6.5 version. I have been trying to find out how to apply these settings in my version.
There is no support to add the samesite setting in Django 1.6.5, that is the reason the adding those in the settings.py did not work. Django 3.1 is where they started this support this setting. I tried adding my own middleware and add the setting to the cookies, but I got an invalid field error. Then I found a library I can use for this - django-cookies-samesite. I was able to apply the samesite setting to None and the secure to True, then I was able to login through salesforce web tab.
Add these in settings.py
SESSION_COOKIE_SAMESITE = 'None'
SESSION_COOKIE_SAMESITE_FORCE_ALL = True
SESSION_COOKIE_SECURE = True
CSRF_COOKIE_SECURE = True
And add this in the MIDDLEWARE_CLASSES:
'django_cookies_samesite.middleware.CookiesSameSite',
Relevant sites I got the info from:
https://github.com/django/django/pull/8380/files
https://pypi.org/project/django-cookies-samesite/

How to fix mixed content error in Swagger?

I am running Django RF backend application on Gunicorn.
When trying to fetch data from Swagger I get "TypeError: Failed to fetch"
In console this error is reported:
Mixed Content: The page at 'https://****.com/swagger/' was loaded over HTTPS, but requested an insecure resource 'http://****.com/v2/products/'. This request has been blocked; the content must be served over HTTPS.
I tried everything I found and could think of including:
Adding
secure_scheme_headers = {
'X-FORWARDED-PROTOCOL': 'ssl',
'X-FORWARDED-PROTO': 'https',
'X-FORWARDED-SSL': 'on'}
to Gunicorn
and
USE_X_FORWARDED_HOST = True
SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https')
to Django settings.
But nothing helps.
Swagger for Django: drf-yasg==1.12.1
I found the solution. In Django settings add
SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https')
SESSION_COOKIE_SECURE = True
CSRF_COOKIE_SECURE = True
# Security Headers
SECURE_CONTENT_TYPE_NOSNIFF = True
SECURE_HSTS_INCLUDE_SUBDOMAINS = True
SECURE_HSTS_PRELOAD = True
SECURE_HSTS_SECONDS = 3600

Configuring Django Production Settings and Content Security Policy

I'm trying to configure my site to pass the tests at:
https://observatory.mozilla.org
https://csp-evaluator.withgoogle.com/
I've been looking at this blog post. I'm using the Django app called django-csp to implement this. My Django settings in production are as follows:
# Content Security Policy
CSP_DEFAULT_SRC = ("'none'", )
CSP_STYLE_SRC = ("'self'", "fonts.googleapis.com", "'sha256-/3kWSXHts8LrwfemLzY9W0tOv5I4eLIhrf0pT8cU0WI='")
CSP_SCRIPT_SRC = ("'self'", )
CSP_IMG_SRC = ("'self'",)
CSP_FONT_SRC = ("'self'", "fonts.gstatic.com")
CSP_CONNECT_SRC = ("'self'", )
CSP_OBJECT_SRC = ("'none'", )
CSP_BASE_URI = ("'none'", )
CSP_FRAME_ANCESTORS = ("'self'", 'https://example.com/', 'https://example.com/')
CSP_FORM_ACTION = ("'self'", )
CSP_INCLUDE_NONCE_IN = ('script-src',)
CSRF_COOKIE_SECURE = True
SESSION_COOKIE_SECURE = True
SECURE_CONTENT_TYPE_NOSNIFF = True
SECURE_BROWSER_XSS_FILTER = True
SECURE_SSL_REDIRECT = True
X_FRAME_OPTIONS = 'DENY'
SECURE_HSTS_SECONDS = 60
SECURE_HSTS_INCLUDE_SUBDOMAINS = True
SECURE_HSTS_PRELOAD = True
Yet, when I run the aforementioned tests I fail even though I have the above setup. Moreover, in Chrome dev tools I receive no errors, which is great.
Anyone have advice on this please?
Thanks
Update:
I'm deploying the app via Heroku. When I test the appname.herokuapp.com url with Mozilla Observatory, I pass all the tests.
It seems that when I forward the domain appname.herokuapp.com to mywebsite.com, some settings are skipped? I failed the tests with mywebsite.com
I have added the CNAME www to be the value of the custom Heroku DNS.
Indeed, my issue was in the way I had configured my DNS settings. I kept my Django prodution settings as is (see above).
I added a custom domain in my Heroku settings and used the auto-generated server name in my CNAME settings in Cloudflare.
Then I ran a check in Mozilla Observatory and passed the tests.

Can't access csrf cookie sent by server via Set-Cookie (Django + Angular2)

I'm experimenting with an app running on Angular 2 in the frontend and Django as API and I can't access the CSRF cookie sent from Django.
As you can see, I am getting back the cookie from the server but I cannot access it from the browser (document.cookie) or Angular 2 (using the ng2-cookies module).
Everything was working while testing on localhost, now client and server are running on different hosts and this might be the reason of the problem.
Client running on https://django-angular2-movies.firebaseapp.com/
Server running on https://glacial-shore-18891.herokuapp.com
This is part of the settings I'm using on Django:
settings.py
CORS_ORIGIN_ALLOW_ALL = True
CORS_ALLOW_CREDENTIALS = True
CSRF_COOKIE_SECURE = False
CSRF_TRUSTED_ORIGINS = ['django-angular2-movies.firebaseapp.com']
ALLOWED_HOSTS = ['*']
Other things that I have tried, but didn't help:
Removing the CSRF_TRUSTED_ORIGINS setting
Adding CSRF_COOKIE_DOMAIN = 'django-angular2-movies.firebaseapp.com'
Using { withCredentials: true } in the request sent from the client
Using the #ensure_csrf_cookie decorator on Django views
What am I doing wrong?
Thanks
