Can the OPCUA client actually connect to the IOTF platform ? (as that is what the error message implies it is trying to do). I didn't think they spoke the same protocol.

Hi @dceejay I too face similar issue. I hosted Node-RED on IBM cloud and trying to connect Kepware using OPCUA. I couldn't able to connect to endpoint due license issue. How and where can we get certificate when we are using Node-RED on cloud platform?
