Hi, I have an application running and I want to use an external OPC client to connect to the OPC server and read the tags, how I can do that?

Enable "Expose Tag Providers" in the OPC UA server settings (make sure to restart afterwards): [Ignition's OPC UA Server | Ignition User Manual](https://docs.inductiveautomation.com/docs/8.1/ignition-modules/opc-ua/ignitions-opc-ua-server#advanced)

After this, connect a 3rd party client like UaExpert as a sanity check.

I end up creating a new OPC UA user and send the credentials to the client
