I think for me it worked on the first try. If there is an issue with the node server, you can try to create an issue on the GitHub repo and see if the creator replies.
The first thing I would try is to use Hue’s debugger to verify that your PC can ping your Bridge at all. There could be something tricky about the network.
It looks like there were also some recent updates to the Hue API that might limit local discovery methods?
