Cannot connect externally to nginx deluge reverse proxy

Question

I am running Deluge on my Raspberry Pi 3, and everything is working amazing, except I want to connect to it outside of my network. I have tried everything, disabling the UFW rules, correctly port forwarding to my Pi, you name it. I followed this guide to set up a reverse proxy using nginx. I got it to work locally, but when I attempt to use my external IP, it doesn't work. Here is my script that I used from the tutorial:

server { 
listen 80; 
server_name _; 
location /deluge {
 proxy_pass        http://127.0.0.1:8112/;
 proxy_set_header  X-Deluge-Base "deluge/";
    } 
}

I have port 80 TCP forwarded for my Pi, and still it doesn't want to accept any external IP's. I can provide any additional information upon request, sorry for the lack of info, I am currently away from home. Thanks!
