Sorry we can't tell you what is wrong based on this rough information. It could be your Unity Configuration or the OPC Server configuration .....
To be able to check it we would need an example based on an OPCServer we can test with.
Please try to rebuild your problem based on UaCPP C++ Demo server (will send you a download link for this test server in a private message later).
Please upload your project where you can reproduce your problem based on UaCPP Demo server here: https://game4automation.com/send
Please try to change OPCUA_Node.cs like this (about line 364):
We already changed that for the next relaease.
Each time a new OPCUA node is collected, the data is successfully connected but cannot be updated in real time
Please help me in time
