Webradio stops often at random times.

I’m using Volumio 2.502 and when i try to hear internet radio there are often but irregular timeouts from a few seconds to indefinite. Sometimes it helps when I try to push play again, sometimes that doesn’t work either. Spotify does work without problem though.
In this log logs.volumio.org/volumio/R770kVY.html I have timeouts at 15:06, 15:12, 18 and 15:21 for a few seconds to ~1 minute. Can anyone spot anything suspicious?
