Failed connection with TV after a few minutes

Hello,

Each time I start Serviio server, everything runs well : I can browse my movie library, I can launch a movie...
But after a few minutes (even with no activity with Serviio), if I browse my library again or i want to launch a new movie, it does not work, meaning that my library is not accessible from my TV anymore.
On Serviio console, my TV is not recognized as a Sony TV anymore but as an unrecognized device. Aand a new device has been added with IP address 192.168.27.14 (always the same) and the correct profile (Sony Bravia TV 2011)
I have tried with 0.6x, 1.01 and 1.1: I have got the same problem.

Thanks for your help

Here is my config:
- TV: Sony 40ex721 with the lastest update
(connected by wifi or hardwired through a router: in both cases, I have got the problem)
- Serviio (now 1.1) running on a PC with Windows 7 64-bits Ultimate
- Local network: fixed IP address on every item
I have attached a Log file and 2 screen copies of Serviio console when it works and after the problem appears.

The IP addresses aren't the tv different interfaces i.e the wired and wifi connections ?

I do not think so: today, only the wifi connection is enabled and no ethernet cable is connected to the TV
According to a tool I use to watch my local network, 192.168.27.14 does not exist on the LAN: this IP address only appears on the device list of Serviio console.

What is strange to me is that, after a few minutes after the problem appears, (look at the log file) 193.168.0.20 is "associated" to a different uuid (different from time to time) than the Sony tv one (uuid=00000000-0000-1010-8000-00a0969669be). So, Serviio cannot recognize the Sony tv and applied the generic dlna profile and consequently, I cannot see Serviio library on my tv anymore.

How does Serviio server know that he is talking to a Sony TV? through the uuid of the device? another info?

enable detailed logging so that we can see the incoming request and why it doesn't assign the right profile.

Here is a detailed logging.
I stopped and started again Serviio server at about 18:42.
Sony Bravia TV 2011 profile is assigned to the right IP address 192.168.0.20 (my Sony TV)
At about 18:49, 192.168.27.14 appeared on Serviio device list (after refreshung the list)
and the generic DLNA profile is assigned to 192.168.0.20

It looks like the TV announces itself with 2 IP addresses, but with the same ID. So the initial right IP is then updated (because the ID is the same) to the wrong IP. When a request comes from the original IP, no renderer with that IP is found, resulting in Generic profile.

This looks like either a router or TV setup problem. I remember reading about similar issue before, try searching the forum.
