WebOS Playback stop every 10s

[f7_s75yj-n21l]

So, I have a premium Plan on Indonesia, and im playing it on multiple devices, but when i do play it on my WebOS (LG 43UM7300) with Software version 04.71.30.

I Have some trouble while playing any song on "Screen Off" Mode, Does anyone have any idea whats happening? 

Thank you so much for your reply,

Cheers,
