Server Version#: 1.19.4.2902
Player Version#: 4.29.6 on WebOS 5.0.0
After getting a new TV and setting up, the LG Plex player did not recognize the Plex Media Server as nearby.
My network is setup as 10.255.0.0/16. DHCP devices get an address in 10.255.1.0 through 10.255.1.255. Plex Media server is 10.255.0.255.
Turns out, changing the IP of the TV to the 10.255.0.x range, fixed the issue. This means that something in the code is incorrectly using /24 as a standardized subnet, instead of using the actual network subnet, to determine if the Media Server is local.
Please fix. =)
