XBMC/Serviio interoperability

I wonder if someone could help with this. I've got the setup below:-

Media Server: Serviio 1.4.1.2\Ubuntu 12.0.4
Media Client: XBMC 13.2\Windows 7
Network setup:-

Media Server (192.168.0.3) <---> Router <---> Devolo DLAN500 <------ Powerline ------> Devolo DLAN200 <---> Media Client (192.168.0.8)

From XBMC (which I've configured as a UPnP client), I'm trying to browse for the Serviio UPnP server - however Serviio is just not appearing in the list.
I did a wireshark trace of traffic between the client and server - which I've attached - I'm not very experienced at interpreting these traces but it appears that the client and server are talking to each other. The chat between the client and server appears to end with the following exchange:-

client: GET /deviceDescription/c5db91ac-54f5-3daa-b7ba-6fea634c26b1 HTTP/1.1\r\n
server: HTTP/1.1 403 Forbidden\r\n

When I get home tonight, I'll try plugging the laptop directly into a port on the router and see whether that makes a difference. In the meantime just wondering if anyone has any suggestions/pointers?

make sure you have the device enabled in the device list in serviio console (righ-click on the device). There is also a checkbox for automatically enable all new devices in there.

Thanks - this is working now.

For the record, the client device (192.168.0.8) was already listed in the serviio console - but had a red dot next to it. I deleted the client device - then browsed again from XBMC -worked fine.

I 'm a bit puzzled how this situation came about in the first place - the client device is a laptop that has both a wireless and ethernet connection - sometimes I disable the wireless connection and use the ethernet or vice versa depending on where I am. If a client has previously connected to serviio over a wireless connection, would serviio complain if you connected over another interface - or does it not care?

Thanks again for your help.
