[PD] newbie probl. with oggcast~

[kiilo]

hi 

i have some problems 
with oggcast~ and icecast2 on 
winXP

when i try to connect to the icecast2 server 
running on the same machine i get allways this error ...

oggcast~: logging in to IceCast2 server...
oggcast~: logged in to http://gelb01:8000/test01.ogg
oggcast~: ogg/vorbis encoder initialised
error: oggcast~: could not send ogg header to server (-1)
oggcast~: closing due to error...
oggcast~: connection closed

I read the HOWTO but i dont get any idea what is wrong?

i modified the help-oggcast~.pd example
and changed passwd to hackme
and the mount point to test01.ogg

in the icecast2 configuration i only changed

<fileserve>test01.ogg</fileserve>
as mountpoint  

there are no firewall rules, all ports are possible

I hope this is not OT because 
due to an IceCast2 missconfiguration ...

why oggcast~ cannot send this -*@!-header?

best thanx 
for some hints ...
kiilo
