Interrupted Internet Radio LMS 7.9.2

Hello,

I have a LMS 7.9.2 installed on a Raspberry Pi 4 - I play local music, spotify and internet radio. Everything works fine except internet radio which play with interruptions of a few seconds every couple of minutes.

If I am logging "internet radio" I get something like:

[21-03-14 13:02:09.3967] Slim::Web::HTTP::processURL (763) processURL Clients: 192.168.1.64:48552 192.168.1.19:40926 192.168.1.66:51678 192.168.1.61:42652 192.168.1.68:41782 192.168.1.17:53378 192.168.1.62:49329 192.168.1.63:33934

There was an interruption at 13:30 (if that entry really points towards the reason?) but between 13:03 and 13:30 there were several that did not show up at all.

Any idea what else I can log to get closer to the problem's solution?
