M3u8 radio stations only play the first 30 seconds

Dear All,
I installed Mopidy - upmpdcli on a RPi 3 with no issues. I can play most anything just fine. The only issue I am facing is that when I try to play a radio station that has its URL in a *.m3u8 format, Mopidy plays it only for 30 seconds, then it stops.

I am particularly interested in this radio station: RTÉ lyric fm
As far as I can see, this is the actual stream: https://www.rte.ie/manifests/lyric.m3u8

My effective config:

The most annoying thing is that I used to be able to listen to the same station properly until a few days ago, when (due to a crash) I had to rebuild the RPi. So it is definitely possible, I just don’t know what changed. Previously I had a pretty much straightforward, standard installation, no special tweaking for this station.

If anyone has more experience with this sort of things, I’d much appreciate some help…

Thanks in advance!
