Audio is transmitted not by the helionet server, but by my own, private server. This radio server has a administrative interface, that contains statistics related to the broadcasts, that are available at at the indicated port 8000, and that can be displayed e.g on a webpage on a hosting server. But that requires port 8000 to be open on the helioserver to be able to receive these statistics. The amount of data that is sent via 8000 is relativly low, so this can hardly be any problem for the heliohost server ! In the mean time this problem is solved ! Thanks to Krydos. So the answer to Krydos question "Is it working now?" is : YES !!! Thank you very much !
