Nginx does not display custom 404 page with Gunicorn + Flask

I'm trying to display a custom 404 error page on my site, but it seems that Nginx does not catch the 404. Instead, it shows a 404 page from Gunicorn(flask app)

nginx.conf:

server {
listen 80 default_server;
server_name example.com www.example.com;

location / {
    proxy_pass http://flask:8080/;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $host;
    proxy_redirect off;
}

error_page 404 /notfound.html;
location /notfound.html {
    root /var/www/html;
}

error_page 500 502 503 504 /maintenance.html;
location /maintenance.html {
    root /var/www/html;
}
}

Both flask app and Nginx are running on separate docker containers.

I purposefully brought the flask app down to see what happens, after a while It redirects to 504(Timeout) and the maintenance.html appeared. - works fine.

But on a 404 error instead of displaying this custom notfound.html, it displays a 404 Not Found from Flask App (The 404 page did not had any nginx version on it).

proxy_intercept_errors on; should solve this problem.
