Audio Stream on AU335

Hi there,
I would like to play an audio stream on an AU335 (radio station).
The stream link is http://wdr-1live-live.icecastssl.wdr.de/wdr/1live/live/mp3/128/stream.mp3
Unfortunately the player doesn't play anything.
A local mp3 will play correctly.

Can you help me with this?

Greetings, Sören
