Thanks for the report, we’ll get this fixed. You can delete that connection and create a new one (or just leave it be if it doesn’t let you delete it) in the meantime if you want to continue to try the 7.2 beta. ---

I just received the same problem after updating to 7.2 I could not delete it due to the module that installed it is unavailable (now running OPC UA Module 1.2.0-beta1 (b6280)) ---
