Issues with instrument control via ethernet

Hi,

I'm quite new to LabView. I am trying to communicate with my SR DG645 delay generator via ethernet. I followed the steps discussed NI 'Ethernet Instrument Control Tutorial' (https://knowledge.ni.com/KnowledgeArticleDetails?id=kA03q000000x3gXCAQ&l=sv-SE). I managed to succeed in the steps but when finally the system added in NI MAX devices and interfaces, it shows a red mark (see attached image), and as a result, I can't do the Test Communication in VISA Test Panels. I also attached the test result of communicating with my instrument over the network. Could any of you help to resolve the issues?

Thanks in advance,

Chemra.
