OPC-UA Connection broke after version upgade

Ignition
1

Hello,

We’ve just performed Ignition upgrade from 7.8.2 to 7.9.10. We also upgraded Windows Server from 2008 to 2016 at the same time. Everything went smooth except for OPC-UA connection - server is no longer discoverable by other gateways. Here are error messages we are getting:

====
java.util.concurrent.ExecutionException: UaException: status=Bad_ConnectionRejected, message=java.net.ConnectException: Connection refused: no further information: ABCD.DOMAIN.com/10.XXX.XXX.XX:4096

org.eclipse.milo.opcua.stack.core.UaException: java.net.ConnectException: Connection refused: no further information: ABCD.DOMAIN.com/10.XXX.XXX.XX:4096

java.net.ConnectException: Connection refused: no further information: ABCD.DOMAIN.com/10.XXX.XXX.XX:4096

Any help is appreciated.

Thank you,
Peter.

Can you show us a screenshot of the UA Server configuration page in the gateway?

Kevin, here are OPC-UA server settings on the gateway:

Try replacing whatever hostname you’ve got in the Endpoint Address with the IP address and then restart…

Either the server isn’t binding to the right address or there’s something else entirely going on, like a firewall preventing the inbound connections.

Changing hostname to IP and restarting gateway did the trick.

Thanks a lot, Kevin!
