HI,

I get this error: "Gurux.DLMS.AMI.Agent.Worker.GXAgentWorker[0] Failed to establish the connection. Value cannot be null. (Parameter 'PortName')" after connecting the agent and adding a new task. The connection is successful but once a task is added, it throws the error above.

Thanks for your help.
