DLNA DMR Component Periodic Connection

HI all,

perhaps someone can help me out here. I am trying to connect a Busch Jäger Inet radio via DLNA renderer to home assistant. I can connect the radio to BubbleUPNP this work perfectly, but in HomeAssistant it connects and disconnects from the device every 3 seconds. I assume that the event handler is not passed correctly, but I have no idea how to proceed. Can someone help me out here?

Attached is the debug Log which shows the disconnect:

Further I copied in the XML files of the radio:
