Hello Small People

          I am new to the PI system and please give me some instructions on troubleshoot. 


          I have a connection issue between Node-Red and Pi Web API. The Node-Red software is installed in Ubuntu. The two PCs (Node-Red and PI system) are under the same network. In Node-Red, I install the node of Osisoft Web API (Please see links below). Then I followed the tutorial (Tutorial: Using the OSIsoft PI Web API node with FRED (Cloud Node-RED) | Sensetecnic Developer )  and tried to test the connection. I always get an error message, "Error: getaddrinfo ENOTFOUND desktop-tc061b4 desktop-tc061b4:443". The "desktop-tc061b4" is my Server Name.


          What's the Server URL? It seems like the Node-Red cannot locate the PI Web API. What's the correct Server URL? Could you please give me some suggestions? thanks
