Ok, some more findings. I enabled debug logging on org.eclipse.smarthome.config.discovery.upnp and org.jupnp and now I get more useful info in my logs. I get things like this:
09:26:24.138 [DEBUG] [jupnp.transport.spi.MulticastReceiver] - UDP datagram received from: 192.168.168.40:57917 on local interface: eth0 and address: 192.168.168.3

From what I understand it fails fetching the device_description.xml, right? Strange thing is I tried fetching the exact same URL from the server (using wget) and that works fine and I get an ok looking xml file. So why doesn’t the binding succeed in getting the same xml?
