Is it secure to set SECURE_SSL_REDIRECT=False if I have nginx setup as a reverse proxy serving the site over https?

I can access the site over SSL if this is set this to False, where as if it is True, I receive too many redirects response.

NOTE: nginx and django run from within docker containers.

My nginx.conf looks like:

upstream config {
    server web:8000;
}

server {
    listen 80;
    server_name _;
    return 301 https://$host$request_uri;
}

server {

    listen                  443 ssl;
    server_name             _;
    ssl_certificate         /etc/ssl/certs/cert.com.chained.crt;
    ssl_certificate_key     /etc/ssl/certs/cert.com.key;

    location / {
        proxy_pass http://config;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $host;
        proxy_redirect off;
    }

    location /staticfiles/ {
        alias /home/app/web/staticfiles/;
    }

}

EDIT: Added http to https redirect in nginx.conf.
