Connection problem

[LukasHiereth]

i'm getting the following error, after added my controller to homebridge and try to switch the led stripe on or off.

[Sunricher] SunricherService: send message error 'connect ECONNREFUSED 10.10.60.61:8889'
 Error: connect ECONNREFUSED 10.10.60.61:8889
    at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1187:16) {
  errno: -111,
  code: 'ECONNREFUSED',
  syscall: 'connect',
  address: '10.10.60.61',
  port: 8889
}

i testet with

nc -vz 10.10.60.61 8899

if the port is reachable and it is

Connection to 10.10.60.61 8899 port [tcp/*] succeeded!
