What server are you trying to connect to? Is it running on another machine or the same machine? Are you sure it’s actually running and you have the right hostname and port? The error you’re getting is just a standard TCP connection error: connection refused. If not a firewall issue this usually means there’s just not anything actually listening at that address/port. ---

So you’re trying to create another connection to Ignition’s own OPC UA server then? Try using “localhost” in the endpoint URL instead of “192.168.0.24”. ---

If it’s the same error message even when using localhost then maybe the server is failing to bind on startup. You might want to get in touch with support so they can take a look at an export of your logs. ---
