Django+Wordpress+Nginx reverse proxy apache - django

Question

I have 2 machines one is django (https://orgofoods.com) and another one is wordpress (https://blog.orgofoods.com). Django is running with nginx, gunicorn and the configuration goes like this
upstream app_server {
server unix:/home/django/gunicorn.socket fail_timeout=0;
}
server {
root /usr/share/nginx/html;
index index.html index.htm;
client_max_body_size 4G;
server_name orgofoods.com;
keepalive_timeout 5;
# Your Django project's media files - amend as required
location /media {
alias /home/django/django_project/django_project/media;
}
# your Django project's static files - amend as required
location /static {
alias /home/django/django_project/django_project/static;
}
# Proxy the static assests for the Django Admin panel
location /static/admin {
alias /usr/lib/python2.7/dist-packages/django/contrib/admin/static/admin/;
}
location /blog {
proxy_pass https://blog.orgofoods.com;
}
location /blog/wp-content {
proxy_pass https://blog.orgofoods.com/wp-content;
}
location /blog/wp-includes {
proxy_pass https://blog.orgofoods.com/wp-includes;
}
location /blog/wp-login.php {
proxy_pass https://blog.orgofoods.com/wp-login.php;
}
location /blog/wp-admin {
proxy_pass https://blog.orgofoods.com/wp-admin;
}
location / {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_redirect off;
proxy_buffering off;
proxy_pass http://app_server;
}

server {
if ($host = orgofoods.com) {
return 301 https://$host$request_uri;
} # managed by Certbot
listen 80 default_server;
listen [::]:80 default_server ipv6only=on;
server_name orgofoods.com;
return 404; # managed by Certbot
}
but when i try to access orgofoods.com/blog it is returning 404 error, and the request is handled by nginx where as it needs to be handled by apache, please any one can shed some light on it.
