[PLUGIN] YouTube Music

Hi, short question, I don’t know whose “fault” it is:
I access volumio, which is running on a proxmox VE*), through different devices (laptop, phone etc.) using its static IP adress. Once I start the music search from another device, the music stops playing. Is there a reason for that? It used to be playing until I eventually clicked one of the search results. Or is it volumio’s or even proxmox’ fault?
