[SOLVED] TV doesn't see Serviio

Untill a month ago Serviio was working fine on my entirely wireless network, but my Bravia 32CX520 started skipping files or dropping the connection entirely. So now I have connected the TV to the router with a lan-cable, but the TV doesn't see Serviio nor does Serviio see the TV. The TV-internet is fine, better than before, so the connection is fine. And it does recognise the Windows Media Player server on my PC on which I also run Serviio. So it can make some sort connection.
I have opened the TCP- and UDP-port described in other solutions and set the bound IP address to the address of the server on the PC (the only bound address it allows). And I have cleared the list of servers on the TV and on the console and restarted, but still Serviio won't recognise the TV, nor the other way around.
So what is wrong?
All help is highly appreciated.
