Volumio switches off after a few hours

Volumio turns off after a few hours. I have Volumio installed on a Raspberry Pi 3 and connected to a LAN cable.

In my Fritz box 7490 I have fixed the Ip address.

Volumio is to play a Radiostream continuously. Unfortunately, the stream the next morning off.

The Raspberry Pi is still accessible.

Can someone help me?

Maybe your issue is related to mpd not restarting when the data stream is interrupted. Look into a MPD Watchdog. github.com/tkem/mpd-watchdog
