spring boot - OpcUA connection failed

Question

I'm sorry for the question, but I'm new to Milo and I'm trying to use the apache - camel - milo version, in a SpringBoot application. I try to read a data but I can't connect with the application but only with UaExpert. To make it easier I have the server configured to accept connections with a security policy of none. I enclose error and configuration. Can you give me some advice?

<springboot.version>2.4.2</spring.version>
<camel-milo.version>2.25.3</camel.version>

Application.properties

                .routeId("Test router id1")
                .log("From OPC UA: ${body}")
                .process((Exchange exchange) -> {                    
                    String routeId = exchange.getFromRouteId();
                    DataValue data = exchange.getIn().getBody(DataValue.class);
                    
                    System.out.println("Route  : " + routeId);
                    System.out.println("Status : " + data.getStatusCode().toString());
                    System.out.println("Type   : " + data.getValue().getDataType().getClass());
                    System.out.println("Value  : " + data.getValue().getValue());
