How to get the Device's Network Information?

Good evening,

We are trying to get the device's network information as described in the documentation "Common Information > WebAPI Specification > Device Setting: Network", by using the example as shown at "SmartOperation Panel > Sample Applications > Obtain Machine Information", however we are getting the following return:

System.out: NETWORK: http://gw.machine.address:54080/rws/property/network

03-10 16:35:34.158  8286  8780 E NDDPRINT --- : logic:MachineSSL:com.nddigital.nddPrint.wrapper.common.InvalidResponseException: 404 Not Found

03-10 16:35:34.158  8286  8780 E NDDPRINT --- : logic:MachineSSL:Request failed.

03-10 16:35:34.158  8286  8780 E NDDPRINT --- :   Error code = 404

03-10 16:35:34.158  8286  8780 E NDDPRINT --- :     error.path_no_exist : 

Is there any setting to be performed? Or even a new sample on how to get these network information?

Best,

Guilherme Júlio
