Hi, newbie here and struggling to get my connection setup for the first time. The issue is identical to that highlighted in [[OPC-UA Server connection refused](https://forum.inductiveautomation.com/t/opc-ua-server-connection-refused/39081)]([https://this](https://this) topic), only the solution highlighted there isn't working for me, or I am misunderstanding it. Upon changing my endpoint from local point to the IP address I am presented with UaException: status=Bad\_ConnectionRejected, message=io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: no further information: /192.168.0.241:62541 ![Ignition Bind

Are you trying to connect Ignition to another server or connect another client to Ignition? Changes to the settings in your screenshot require a restart to take effect. ---

I'm following this video tutorial on setting up connection to a S7-1200.

I don't know who created this video and have not watched it yet, but setting up a connection to another OPC UA server does not involve the settings you are messing around with. ---

I'm struggling with the very first step before even getting to the point of setting up the link with the PLC, which I believe though could well be mistaken is the server to client configuration. I got to the those settings as that was a solution you proposed in the other linked post to a user who had what appeared to be the same issue I was having when trying to change the endpoint url to my PC's IP address from localhost. I will read through the official documentation tonight as there is some fundamental concept or terminology I haven't grasped yet around how this works.
