If the client is on another host then you probably also need to change the Bind Address to something like 0.0.0.0.

After changing any of these settings you'll need to restart the Ignition Gateway.

You would need to make sure that you've run your Docker instance with port 62541 on the host forwarded to port 62541 on the container, e.g. with `-p 62541:62541`.

You should be able to point UaExpert at `opc.tcp://localhost:62541/discovery` after that.
