I’m a student who wants to create a digital twin environment using opc ua.
I purchased an opc ua server from a robot company. And Through this, i want to extract robot data and receive it to unity.
So I strated the first step, extracting data from the opc ua server, but i got an eerror right away.
The problem came when i was trying to extrat data from the server using a c# script.
The error message said connect error. So I tried other scirpts that I found on the internet, but the same error was repeated.
Also the C# scripts I used first was from where I bought the server, so it doesn’t seem to be a problem wih the script.(because the company said it worked well when they tried it with same c# script )
The irony is that the server works well when connected as an UA Expert.
This is my first time using OPC UA, and I can’t find the cause of the problem, so I want to ask for help.

You can find working C# samples here:
https://github.com/OPCFoundati…..enceClient
See if you can get that to connect.
Note that you have to have a certificate configured for your client if you want to use security and UA server always requires security by default. You may be able connect if you disable security on the server temporarily.
