webos port 3000 not open
Hi,
I'm trying to configure WebOs LG tv with homebridge. 
I already configured homebridge and see all the button via GUI & HomeKit
but when I'm trying to turn on/off or any other command - nothing happen
with homebridge -D I can see the below issue -
someone can assist how to open this port? I already enable "Mobile Tv" option at the LG TV
