Samsung UN55E6100F TV does not see Serviio

I've made sure that the TV is current, the hub updated recently and I just updated the TV software to 02004 and neither helped.

When I hit Source, it doesn't see Serviio. It's worked in the past but it doesn't work now. I can't say when it started because I only use it every so often, so it could have vanished at any time.

I am running Windows 7 Pro (64bit)
I've not changed any settings, on the TV or PC from when it last worked to now.

Windows firewall is disabled and it's currently on the routers DMZ (All ports open) for the duration of my troubleshooting.

PC IP: 192.168.1.137
TV IP: 192.168.1.138

The Serviio service is running and set to Automatic, restarting the service and that didn't help. Updated Serviio to 1.5.2 and that didn't help either.

The TV's network is working fine, I can use Netflix etc.

Checked the other threads and they haven't helped.

Any suggestions?

On the Serviio console, there's a box that tells Serviio what IP address to use. Your IP address doesn't look like it's been set as a static, so it's possible the console is telling it to use an address that the computer isn't using. See if it's set to automatic or to a specific IP. You can also look at the log for when Serviio first starts and make sure it's using the correct IP address.

If all is well there, then there are more steps to check. Let's start here first.
