Live radio streams cutting out [closed]

I have a problem with live radio streams constantly cutting out for about 15 seconds or so but at random intervals. Specifically with radio stations from the Rayo service and direct streaming connections to Solar Radio. This happens on hard wired devices as well as WiFi connected to Gigaclear broadband. Other streaming such as Spotify and video such as Netflix works just fine. If you play a pre-recorded show from Rayo or Solar, that works just fine too. If I’m listening on a mobile device and switch from the broadband to mobile data, that works just fine too. I’ve tried monitoring the broadband connection but there is nothing untoward. I have also tried a static IP address from the ISP too. Any ideas?
