"The torrent list is not available yet, the connection to rtorrent has not been established" with RPC SOCKET

[ephedan]

Environment

• Web Browser: Safari Version 18.2 (20620.1.16.11.8)
• rtorrent : 0.9.8-1 arm64
• ruTorrent: v5.1.2
• Web Server : 1.4.69-1 arm64
• PHP: PHP 8.2.26 (cli) (built: Nov 25 2024 17:21:51) (NTS)
• OS: Debian 12

Error message

• "The torrent list is not available yet, the connection to rtorrent has not been established"

Context

• I have made a first working installation using host and SCGI port.
• I now want to use RPC SOCKET.

For configuration I used the following pages:

1. https://github.com/Novik/ruTorrent/wiki/MainInstall
2. https://github.com/Novik/ruTorrent/wiki/WebSERVER#lighttpd-specific-scgi-config
3. https://github.com/Novik/ruTorrent/wiki/Config

Question

How do I solve my connection problem between rtorrent and rutorrent?

rtorrent.rc

method.insert = cfg.basedir,  private|const|string, (cat,"/home/rtorrent/")
method.insert = cfg.session,  private|const|string, (cat,(cfg.basedir),".session/")
session.path.set = (cat, (cfg.session))
network.scgi.open_local = (cat,(session.path),rpc.socket)

this gives us network.scgi.open_local = /home/rtorrent/.session/rpc.socket

config.php

	// For web->rtorrent link through unix domain socket
	// (scgi_local in rtorrent conf file), change variables
	// above to something like this:
	//
	// $scgi_port = 0;
	$scgi_port = 0;
        // $scgi_host = "unix:///tmp/rpc.socket";
        $scgi_host = "unix:///home/rtorrent/.session/rpc.sock";

but ruTorrent looking for: $scgi_host = "unix:///home/rtorrent/.session/rpc.sock"
this should probably be: $scgi_host = "unix:///home/rtorrent/.session/rpc.socket"

these two must point to the same file
