How to proxy calls to specific URL to deluge using NGINX?

4.2k Views Asked by Werolik At 18 April 2025 at 20:36

I want to use NGINX to as a proxy to get to Deluge which is inside my home network (NGINX is publically available).

This configuration works:

location 8112;

location / {
    proxy_pass http://deluge_address:8112;
}

However I'd like to use an address in form of http://nginx_address/deluge to be proxied to internal http://deluge_address:8112.

I tried the following:

location /deluge/ {
    proxy_pass http://deluge_address:8112/;
}

(I tried different combinations of trailing / - none work).

But I get 404 Not found instead.

I have some knowledge about networks, but not too much. Does anybody have any idea what I'm doing wrongly?

I faced the same problem, luckily I found a better and official solution:

Reverse Proxy with Deluge WebUI

    proxy_set_header X-Deluge-Base "/deluge/";
    add_header X-Frame-Options SAMEORIGIN;

My final settings:

  location /deluge {
    proxy_pass http://127.0.0.1:8112/;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "Upgrade";
    proxy_set_header Host $http_host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_connect_timeout 75;
    proxy_send_timeout 3650;
    proxy_read_timeout 3650;
    proxy_buffers 64 512k;
    client_body_buffer_size 512k;
    client_max_body_size 0;

    proxy_set_header X-Deluge-Base "/deluge/";
    add_header X-Frame-Options SAMEORIGIN;
  }

~~I did find a solution for this, but found a bug also in Nginx in the same time~~

Edit-1

Seems like bug i logged was an invalid one, which even helped me understand few more things. So I edited the config a bit.

You need to use below config

location ~* /deluge/(.*) {
    sub_filter_once off;
    sub_filter_types text/css;
    sub_filter '"base": "/"' '"base": "/deluge/"';
    sub_filter '<head>' '<head>\n<base href="/deluge/">';
    sub_filter 'src="/' 'src="./';
    sub_filter 'href="/' 'href="./';
    sub_filter 'url("/' 'url("./';
    sub_filter 'url(\'/' 'url(\'./';

    set $deluge_host 192.168.33.100;
    set $deluge_port 32770;
    proxy_pass http://$deluge_host:$deluge_port/$1;
    proxy_cookie_domain $deluge_host $host;
    proxy_cookie_path / /deluge/;
    proxy_redirect  http://$deluge_host:$deluge_port/ /deluge/;
}

The key was to insert a base url into the pages using below

sub_filter '<head>' '<head>\n<base href="/deluge/">';

And then make replacement in src and href attributes in html. And also url(' in css entries.

Luckily deluge has a JavaScript config which has the base url. So we can override the same by adding

sub_filter '"base": "/"' '"base": "/deluge/"';
