Hi Milco,

●Duplicate IP addresses in use maybe?  
●Is Homey’s IP address in the 192.168._ **68** _.x range?  
●Do you use VLAN’s / multiple subnets?  
●When you install a [Net Scan app](https://community.homey.app/t/app-pro-netscan-version-2-0-6-test-version-2-0-8/47454) “TCP port” device, IP `192.168.68.145` + port `80`, does it detect the nrg print?

If interested, a nice network check tool [here](https://play.google.com/store/apps/details?id=com.appsinception.networkinfo).
