Playback stops random and doesnt work for minutes

[berrywhite96]

Hello,
since yesterday I have the problem that the playback randomly stops and then not work for minutes. Tested on two Raspberry Pi 3 and two internet connections.
Console output:

Requesting Bytes: 1459k => 1590k +131k (used: 691k, buf: 823k, thres: 695k, rate: 320k)

ESDK: callback context (nil), event 7, source: (nil), param (nil)

Thank you.

Edit: Added console output with debug flag.
