Hello,

I am creating a flow with multiple injections for different metrics which all point to their own OPCUA-Client node so that I can create individual gauges/charts for each of them on the UI page.

For some reason, when I go to place the 6th OPCUA-Client node, even with the same endpoint, it says connection error. I have tried everything and it has nothing to do with the endpoint as the others operate fine, and has nothing to do with the injection node. It just seems like I am only allowed to have 5?

Is this the case? If not, how do I fix it? If so, how can I use only 5 while having much more than 5 different gauges/charts for each injection variable?

I attached a screenshot to show. Thanks
