Maybe it fails, because I haven't selected anything to be played? If 
that is the case, then I think the user should be informed through a 
message. I noticed that when I go to random albums (or probably some 
other menu) and press RET on the options listed there I get:

I've pushed a fix for the message error when mpv hasnt started yet/doesnt have anything to play.

Would you be able to send me the body response from 
https://funkwhale.juniorjpdj.pl/rest/getMusicDirectory.view?u=Festerdam&p=my-password&c=ElSonic&v=1
16.0&f=json&id=6321

or any of the failing items? I'm not sure why this would be happening,
it should probably be a message as with the toggle not an error.

Thanks

Not sure if that's what you are asking but this is what curl outputs 
when opening the link:
<!doctype html>
<html lang="en">
<head>
   <title>Not Found</title>
</head>
<body>
   <h1>Not Found</h1><p>The requested resource was not found on this 
server.</p>
</body>
</html>

I can open artists, but albums for some reason cannot be opened.
