I’m getting an OPC-UA Server fault “connection timed out: /10.169.3.20:4096”. I have set my OPC-UA Server Endpoint Address to 10.169.3.99 so I’m not sure why the IP address in the fault description does not match? I have restarted the OPC-UA module and have rebooted the gateway computer several times. Any ideas? Is there a file I can edit to try to change the Endpoint Address manually?

Some additional information: This is a restored Gateway from a machine where the Endpoint Address was 10.169.3.20. Not sure if that helps any?

You probably need to change the OPC-UA connection entry to point to the new address also (under OPC Connections \> Servers).

Good grief! That was it. Never even knew about that one. Thanks for the help.
