Hi,

I was trying to connect to OPC UA client via different OPC UA free servers like Ignition, Prosys OPC UA Simulation Server, Integration Objects OPC UA Server Simulator but was unable to connect to it. 

The Streamsets OPC Client was refusing to connect to it. However, I tried connecting Integration objects OPC client with its server and it was able to connect. 

Can someone guide me through the steps to connect to OPC UA Client and also mention any OPC UA servers.
