Fixing ruTorrent "contentDocument is null" & Iframe 404 Errors in Nginx

Issue:

• When submitting a torrent in ruTorrent, you may see errors like:

  • "contentDocument is null"
  • "GET /<rutorrent_dir_goes_here>/php/addtorrent.php 404 (Not Found)"
    or in my case it was, when adding an upload
    -'"Uncaught TypeError: Cannot read properties of null (reading 'href') "'

• This happens because Nginx is not correctly handling PHP files inside <rutorrent_dir_goes_here>/php/.

Step-by-Step Fix

1: Edit Nginx Configuration**

Open your Nginx config file:

Or, if ruTorrent has a separate config, open it:t

2: Add the Correct Location Block to your config file**

Find your server {} block and add/update these sections:
in my case, nginx
server {
listen 80;
server_name my.domain; # Change this to your actual domain

root <server/docroot/goes_here>
index index.php index.html index.htm;

# Serve ruTorrent at /<rutorrent_dir_goes_here>
location /<rutorrent_dir_goes_here> {
    try_files $uri $uri/ /<rutorrent_dir_goes_here>/index.php;
}

# Serve PHP scripts inside /<rutorrent_dir_goes_here>/php/
location /<rutorrent_dir_goes_here>/php/ {
    try_files $uri =404;
    include fastcgi_params;
    fastcgi_pass unix:/run/php/php8.1-fpm.sock;  # Use PHP 8.1
    fastcgi_param SCRIPT_FILENAME /var/www/html$fastcgi_script_name;
}

# General PHP handling
location ~ \.php$ {
    include snippets/fastcgi-php.conf;
    fastcgi_pass unix:/run/php/php8.1-fpm.sock;  # Adjust PHP version
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
}

}

3: Test and Apply the Fix**

1. Check for errors:

   • If errors appear, fix them before proceeding.

2. Restart Nginx & PHP 8.1-FPM:

4: Verify Fix**

• Open a browser and visit:

  https://my.domain/<rutorrent_dir_goes_here>/php/addtorrent.php

  • If it loads, the issue is fixed!
  • If 404 still appears, check: /var/log/nginx/error.log

Now, ruTorrent should work without errors, and iframe uploads will process correctly!
