Connect EHOSTDOWN
I keep getting the following message:

[13/02/2018, 10:15:46 pm] [LG TV] webOS3 connecting to TV
[13/02/2018, 10:15:46 pm] [LG TV] webOS3 error Error: connect EHOSTDOWN 192.168.0.17:3000 - Local (192.168.0.3:62144)

and then it'll be ok for a short while, and then not OK.

I've tried connecting the home bridge host (A Mac mini) to Ethernet and using Wireless. Same effect.

Network runs DHCP, but the TV has its address assigned to it, so it will always get the same IP address.
