Mopidy suddenly stops every few hours – End of stream on public radio?

I’m listening to a public 24/7 radio station via a continuous MP3 stream. Mopidy however randomly stops playback every few hours and doesn’t resume, as you can see below. I’d like to understand what’s going on here. Whether it’s an issue with Mopidy or the radio station’s server (does it provide a stream with hiccups, which Mopidy just can’t handle?).

If I select the station right after it stops, Mopidy plays again (after the buffer is filled again).
