If Ignition is running on a different host then you will have to modify the Ignition OPC UA server’s bind address and restart it. By default it binds only to localhost. It’s under Config \> OPC UA \> Server Settings in the gateway. You may also need the newest version of UaExpert. Older versions had trouble with Ignition’s default security configuration, which only allows secured connections to the session endpoint URL, including GetEndpoints service calls. The discovery URL would be `opc.tcp://192.168.150.4:62541/discovery` in your case and UaExpert will need to use this URL, which in newer versions will then correctly interpret the response to and make a session against the session endpoint. ---

You should start a new topic, provide complete information on your setup, and complete information on the errors you are getting. {It is probably a bit much to ask for an email conversation--many people on these forums protect their emails. If you want formal IA employee communications, you should probably open a support ticket. This forum is not formal IA support.} ---

If you're connecting from a remote host, and not localhost, you need to adjust the Ignition OPC UA server Bind Address and then restart the Ignition Gateway. By default, it binds only to localhost. Changing the Bind Address to `0.0.0.0` is usually sufficient.
