Why is nginx not serving my static site

Question

I have two applications. One is a Django app and the files for this is located at /home/founders/founders/back

The site is running and you can see it on founderslooking.com

I have another Vue site that forms part of the founderslooking.com site and the files are located at /home/founders/founders/dist

I want the Vue app to run at the location founderslooking.com/app

This is how I set it up. First here is the conf file for the Django site running at founderslooking.com

upstream founders_app_server {
        server unix:/home/founders/founders/run/gunicorn.sock fail_timeout=0;
}

server {
        listen 80;
        server_name founderslooking.com default_server;

        client_max_body_size 4G;

        location / {
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

                proxy_set_header Host $http_host;

                proxy_redirect off;

                if (!-f $request_filename) {
                        proxy_pass http://founders_app_server;
                }

                # auth_basic "Testing";
                # auth_basic_user_file /home/founders/founders/.htpasswd;
        }
        location /static/ {
                autoindex on;
                root /home/founders/founders/back;
        }
}

and here is my set up for the Vue site I need to make run on founderslooking.com/app:

server {
        listen 80;

location  /app/ {
        alias /home/founders/founders/dist/;
        try_files $uri $uri/ /index.html;
        }
}

the conf files are located in sites-available and are called founders.conf and app.conf and I have sim links to those files in sites-enabled.

If I go to founderslooking.com/app/user/1 which is the currently logged in user then I get a Not Found page.

How am I then supposed to host a second site (static) on the same domain? Why is Nginx not getting the index.html file in /home/founders/founders/dist if I go to founderslooking.com/app? Isn't that what the alias /home/founders/founders/dist do?
