There is no source connected or no stream is configured for stream #1

[Naozumi]

Stream ist currently down
There is no source connected or no stream is configured for stream #1

whats does this mean?
when im on the steam as admin and klick on the link behind my streaming source, this text appears..
im shure i only forgot a dumb thing
but the source is definitive connected to the server because i can see the current song name in the server page
