Hello everyone,
A opcua client cannot access to the objects of OPCUA server generate with node-red-contrib-iiot-opcua 4.1.2. Node-red is working over docker, and after reboot problem is solve and there is no problem to connect and read objects and parameters. The thing is that after a time running it seems that OPCUA server is not available. Attached log. What could be the problem? session timeout? Any help? Thank you.
