Django won't get https header - django

Question

Intro
I am building a web app using the latest Django version along with python3.7. The app is dockerized and I plan to deploy with docker-compose. Inside the container, I use nginx to proxy traffic to the application and not expose it directly. Also, I use apache in server level to proxy traffic to various other containers hosted on the same machine.
In the Django application, I use oauth2 to authenticate to Fitbit Web API and the issue I am facing is that the django-social-auth is passing the hostname automatically as a redirect_uri which now, after a lot of configuration with all those proxies, works perfectly in HTTP but when I use HTTPS although the app responds normally the redirect_uri is still http which obviously is not allowed by fitbit and very risky.
Although it is very hard for me to locate in which level the problem occurs I have tried various things but nothing seems to work out.
What I have tried
First
I tried to make my container listen to https request which seemed the most appropriate solution to me but ended getting 502 errors from the Apache.
I tried to find a solution on this by adding some configuration to the virtual host file like
#Solution 1
SSLProxyEngine on
SSLProxyVerify none
SSLProxyCheckPeerCN off
SSLProxyCheckPeerName off
SSLProxyCheckPeerExpire off
ProxyPass / https://localhost:83/ Keepalive=On #Solution 2 (keep alive)
ProxyPassReverse / https://localhost:83
But at last, I found out that it was not an apache issue but that the nginx inside the container was not responding although the traffic was routed to 443 port using HTTPS
Second
I tried to route traffic from the apache https to containerd nginx HTTP ( which does not make so much sense to me ) which makes the application respond normally but and results the redirect_uri error I mentioned above
As you can see I more or less confused and any kind of hint or help could be very useful
Update 1
The nginx configuration as requested in the comments
server {
listen 80;
listen 443 default_server ssl;
server_name localhost;
charset utf-8;
location /static {
alias /app/static/;
}
location /upload {
alias /app/media/;
}
location / {
proxy_pass http://web:8000;
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}

Answer 1

I was able to fix the issue by adding the following configuration on the settings.py. I also added a control conditional in order to be able to run the container in development.
# Was already present before the issue resolved but is also needed
USE_X_FORWARDED_HOST = True
# The actual solution
if eval(os.environ.get('DEPLOY', default=False)):
SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https')
SECURE_SSL_REDIRECT = True
SESSION_COOKIE_SECURE = True
CSRF_COOKIE_SECURE = True
