OPCUA4Unity from G4A 2020.15 still does not connect to the ctrlX endpoints. Only the error message in Unity changed. With other clients like UaExpert from UnifiedAutomation some self-written clients we can connect to the endpoints.

I don't realy remember from which G4A version the OPCUA4Unity is but the main dll has this Version:

Do I only have to try the latest G4A and the OPCUA4Unity of this will potentially do the job?
