I used the browser you sent but error remain same . I am using a third party server and moreover I tried matrikon that worked fine but problem is I have to use third party server for further commissioning of my project. I observed that My server worked fine with Matrikon browser but not With SCADA.
For example, when we got similar error with Inneasoft BACnet OPC server, I wrote to the developer and he implemented all the required methods according to the OPC specification to make the OPC server works with the libraries that are used by Rapid SCADA.
We can try the same approach.
Rapid SCADA uses the official libraries by OPC Foundation. Unfortunately, they are capricious. I hope the future is cross-platform OPC UA.
