How to serve two node.js apps on one domain? Site #2 accessible through localhost but not through url. (Nginx)

I am attempting to run two node.js applications from the same droplet, off the same url. I am serving the first app from http://finleywill.com, and would like to serve the second app from http://finleywill.com/todo.

I am running nginx on the server.

The first app, my portfolio page, listens to port 5000.

• It is served correctly from http://finleywill.com

The second app, a to-do list, listens to port 8888.

• When I go to 67.205.148.223:8888, the app loads.
• However, trying to connect via http://finleywill.com/todo produces a “504 Gateway Time-out”

/etc/nginx/sites-available/finleywill.com is as following:

server { listen 80; listen [::]:80;

    root /var/www/finleywill.com/html;
    index index.html index.htm index.nginx-debian.html;

    server_name finleywill.com www.finleywill.com;

    access_log /root/source/access.log;
    error_log /root/source/error.log;

    location / {
            proxy_pass http://localhost:5000;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host $host;
            proxy_cache_bypass $http_upgrade;
    }

    location /todo {
            proxy_pass http://localhost:8888;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host $host;
            proxy_cache_bypass $http_upgrade;
    }

}

I use PM2 to run the apps as system processes
