[CAN BE DELETED] Debug on Remote Server

[marcorieser]

Hi, I am not sure if I have configured something wrong or what I am trying to do is not possible at all. I have installed Ray locally as an app and the package spatie/ray on the server in the document root. My ray.php looks like this:

return [
    'enable' => true,
    'host' => 'project.tld',
    'port' => 23517,
    'remote_path' => '/home/webs/project/html',
    'local_path' => '/Users/marco/web/project/html',
    'always_send_raw_values' => false,
];

I edit the code locally and when I save it, it is uploaded to the web server. In other words, I don't have a local web server for the project but access the page remotely.
After including the composer autoloader, I call the following code:

ray('My first ray call');

Unfortunately, I don't get any data in the Ray app.
Is this even possible without a local web server? How should the remote server be able to communicate with my local Ray App?
