Why I can not find the server in the localhost? about opc HOT 6 CLOSED

I have never tested the code with IntellutionGateWayOPCServer but it works with most others OPC DA servers. The most common problem is to compile Golang in 64bit when the server is actually 32bit. See also here. Did you try to compile the code with GOARCH=386 (in Powershell: $ENV:GOARCH=386)? Hope this helps.

Thank you for your help
I tried this method，I find that if I list the server with command"localhost",it can not find any server, but if I use my computer name "DESKTOP-UDUBS4F", it can find one server: GrayBoxSimulator, and it still can not find my IntellutionGateWayOPCServer.
My IntellutionGateWayOPCClient can find both GrayBoxSimulationServer and IntellutionGateWayOPCServer.

@konimarti the returned error : Could not load OPC Automation object with wrapper OPC.Automation.1

from opc.

@769139671 The OPC automation wrapper is needed in the Windows COM model to communicate with the server. If you have a standard OPC DA server installation with all the OPC components installed, you usually also get the OPC.Automation wrapper. As an alternative, Graybox provides a free automation wrapper. So, if at least one loads, you should be fine.

It also seems that your OPC server is known for not working well with other clients link.

However, you could add your server's OPC automation wrapper to this package if they provide one. Maybe you should reach out to them.

Regarding your computer name, did you also try '127.0.0.1' instead of localhost?

@konimarti I can find the GrayBoxSimulationServer using cmd command of "list DESKTOP-UDUBS4F",but I can not connect to this server.
If I use "127.0.0.1" instead of "DESKTOP-UDUBS4F", none of server can be found
