[HELP] OPC-UA connection fails with BadSessionNotActivated error

[greg-mcnamara]

Describe the issue I'm testing the OPC-UA connector for the first time with KepServerEx v6 OPC server. I get the following error in the logs when it tries to connect to the server. I'm really not sure if the configuration is correct at all, I'm trying to adapt from the documentation examples.

""2022-01-11 04:13:42" - |ERROR| - [opcua_connector.py] - opcua_connector - run - 121 - "The session cannot be used because ActivateSession has not been called."(BadSessionNotActivated)"

Screenshots from Kepware configuration below:
