Plex Media Server for Mac with a Pansonic Viera TC-P50S30

I have a Panasonic Viera TC-P50S30 that is connected to my home network with a wired connection. I also have a MacBook Pro that is running Mac OS 10.9.1 and Plex Media Server 0.9.8.18 and connected to the network with a wireless connection. Despite the seemingly simple setup, when I go to the DLNA Server option on my TV, I get an error message that says "DLNA server not found". Does anyone know what steps I can take to try and troubleshoot this issue?
