Hi everyone,

with my surprise, I see that the **Ignition OPC UA Server** is faulted.

Here is the error I get:

```auto
UaException: status=Bad_Timeout, message=timed out waiting for acknowledge
	at org.eclipse.milo.opcua.stack.client.transport.uasc.UascClientAcknowledgeHandler.lambda$startHelloTimeout$0(UascClientAcknowledgeHandler.java:134)
	at io.netty.util.HashedWheelTimer$HashedWheelTimeout.run(HashedWheelTimer.java:715)

	at io.netty.util.HashedWheelTimer$Worker.run(HashedWheelTimer.java:503)
	at java.base/java.lang.Thread.run(Unknown Source)

```

What could it be? I don't understand...

Thanks

That isn't the message that matters for this case. That is the client side error (Ignition makes a loopback OPC UA connection to itself). You need to find the error that produces the fault in the server side.

If you cannot find the relevant error, consider sharing more of your wrapper log for us to look at (a chunk from a gateway restart onward), or open a support ticket and share with IA.

Since production wasn't working, I tried to

1. reboot the Ignition service -\> no luck
2. reboot the server -\> it worked!

New year, same trick, I guess
