New TP-Link HS200 Authentication Error With Node Red

I just installed a new TP-Link HS200, configured it to the wi-fi and added it to Home Assistant without a problem.

I want to use Node Red flow to control the switch but it doesn’t show up in entity field of the Node. I’ve noticed an error in the Node Red logs;

TCP 192.168.86.131:9999 Error: connect ECONNREFUSED 192.168.86.131:9999
    at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1634:16) {
  errno: -111,
  code: 'ECONNREFUSED',
  syscall: 'connect',
  address: '192.168.86.131',
  port: 9999
}

Seems the new switch isn’t authenticating with Node Red.

I’ve restarted Node Red as well as Home assistant without success.

FYI: When adding the new switch, I was prompted to enter my TP-Link (Kasa) user account ID and P/W. I don’t recall doing that when the other 40 some odd devices were added some time ago.

What’s going on here? Why is there an Authentication error in Node Red?

I’ve narrowed this error down to the Node-Red kasa node named node-red-contrib-tplink. The new device shows-up in all Home Assistant nodes.

With this knowledge, I’m going to consider this post resolved.
