Can't connect to PLC over VPN

[JessevGool]

Describe the bug
I am unable to connect to a PLC that I am connected to over a VPN. I can connect to the PLC using different libraries just fine but Milo is throwing a timeout.
I am using the following code:

public class Main {
    public static void main(String[] args)  throws Exception{
        OpcUaClient client = OpcUaClient.create(
                "opc.tcp://192.168.30.5:4840",
                endpoints -> endpoints.stream().findFirst(),
                configBuilder -> configBuilder
                        .setRequestTimeout(UInteger.valueOf(10000))
                        .setConnectTimeout(UInteger.valueOf(10000))
                        .build()
        );
        try {
            client.connect().get();
        } catch (Exception e) {
            if (e.getCause() instanceof UaException) {
                UaException uaException = (UaException) e.getCause();
                System.out.println("Failed to connect. Status: " + uaException.getStatusCode());
                System.out.println("Error message: " + uaException.getMessage());
            }
            e.printStackTrace();
        }


        UaVariableNode node = client.getAddressSpace().getVariableNode(Identifiers.Server_ServerStatus_StartTime);
        DataValue value = node.readValue();

        System.out.printf("StartTime=%s", value.getValue().getValue().toString());
    }
}

Additional context
I am using the latest version of Milo, the error doesn't occur when I try to connect to the public server. I also noted that it says 50.50.50.1:4840 in the error and I'm wondering where that is coming from
