Apache Camel Milo Client Timeout

Question

I'm trying to connect to a OPC UA server with camel. I downloaded the camel java template via mvn:archetype. This is what my route looks like:

public class MyRouteBuilder extends RouteBuilder {
    public void configure() {
        from("milo-client:tcp://10.0.75.1:4840")
            .log("From OPC UA: ${body}");
    }
}

No matter what server I try to connect to, I always get:

java.util.concurrent.ExecutionException: UaException: status=Bad_Timeout, message=io.netty.channel.ConnectTimeoutException: connection timed out: /172.17.0.2:4840

The OPC servers aren't the problem, I can reach all of them with any other client.

Am I missing something here? Thank you for your help.

Answer 1

I'd have to guess that your OPC UA server is misconfigured and returning 172.17.0.2 in its EndpointDescriptions instead of 10.0.75.1.

This either needs to be fixed in the Camel/Milo integration, if there's not already an option to override the hostname, or you would need to correctly configure the server to include 10.0.75.1 in its endpoints.
