Problems connecting to a particular stream

Hi guys,
I am struggling to access the "Bayern 2" radio stream through my Logitech Media Server (version 7.8.0 and 7.7.2) and the TuneIn app. When I connect to the stream, while being connected to mysqueezbox.com it plays fine.

On my controller I get the following error message:
Connect timed out. Transport endpoint is not connected.

This is from the server log file:
[12-10-15 19:08:16.6992] Slim::Utils::Scanner::Remote::__ANON__ (240) Error: Can't connect to remote server to retrieve playlist for, http://streams.br-online.de/bayern2_1.asx: Connect timed out: Transport endpoint is not connected.
[12-10-15 19:08:16.7006] Slim::Utils::Scanner::Remote::__ANON__ (240) Error: Can't connect to remote server to retrieve playlist for, http://streams.br-online.de/bayern2_2.m3u: Connect timed out: Transport endpoint is not connected.

Some more information:
LMS is installed on a linux system running RHEL6.3
Lame is not installed - will I need to install it?
Other streams seem to work fine.
I am using a Squeezebox Duet, which is connected to the local network by WIFI with a static IP address.

Any help would be very much appreciated.
Thanks a lot!
Robert
