Samsung TV UE65MUXXXX - newsamsungtv - not working

I install node-red-contrib-newsamsungtv without problems, but when I send key nothing is happening. I adjust the IP, and try to ping TV. 4/4
Do I need to make some other adjustments?

The node is quite specialised, you might have more luck opening an issue against the node on the nodes github page ( you should find a link from the nodes page on )
