Your Environment

Version used: 4.8.2 (stable)
Environment name and version:
- Node.js version node --version: v22.2.0
- npm version npm --version: 10.8.1
- Web browser name and version: Firefox 126.0.1 and Chrome 125.0.6422.142
Operating system and version: Arch Linux
Torrent client and version: rtorrent 0.9.8

rtorrent and flood are set to run as the same user, so that they have access to all necessary directories. flood is running behind a nginx server with the recommended server configuration as follows:

root /usr/lib/node_modules/flood/dist/assets;

location /api {
  proxy_buffering off;
  proxy_cache off;
  client_max_body_size 100M;
  proxy_pass http://127.0.0.1:3000;
}

location / {
  try_files $uri /index.html;
}

Summary

When attempting to add a torrent via file, the client responds that the torrent was added successfully, but the torrent is not added. Adding torrents via magnet works.

I have investigated the xmlrpc logs from rtorrent, it appears that it is receiving the raw_start call containing the base64 encoded torrent, and returning the following:

^@Status: 200 OK^M
Content-Type: text/xml^M
Content-Length: 140^M
^M
<?xml version="1.0" encoding="UTF-8"?>^M
<methodResponse>^M
<params>^M
<param><value><i4>0</i4></value></param>^M
</params>^M
</methodResponse>^M

Expected Behavior

The torrent file should be added in rtorrent.
