Push is only working with localhost:8080

Vaadin 6 / 7 / 8

Hello,

I have the problem that Push isn’t working anymore.

I created a new project

mvn archetype:generate -DarchetypeGroupId=com.vaadin -DarchetypeArtifactId=vaadin-archetype-application -DarchetypeVersion=7.4.5 Edited the MyUI.java file

/**
 *
 */
@Theme("mytheme")
@Widgetset("test.MyAppWidgetset")
@Push
public class MyUI extends UI {
 VerticalLayout layout = new VerticalLayout();
    @Override
    protected void init(VaadinRequest vaadinRequest) {
        layout.setMargin(true);
        setContent(layout);

        Button button = new Button("Click Me");
        button.addClickListener(new Button.ClickListener() {
            @Override
            public void buttonClick(ClickEvent event) {
                layout.addComponent(new Label("Thank you for clicking"));
            }
        });
        layout.addComponent(button);
        new InitializerThread().start();
    }

    class InitializerThread extends Thread {
        @Override
        public void run() {
            // Do initialization which takes some time.
            // Here represented by a 1s sleep
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
            }

            // Init done, update the UI after doing locking
            access(new Runnable() {
                @Override
                public void run() {
                    // Here the UI is locked and can be updated
                    layout.removeAllComponents();
                    layout
                            .addComponent(new TextArea("This is the real UI"));
                }
            });
        }
    }

    @WebServlet(urlPatterns = "/*", name = "MyUIServlet", asyncSupported = true)
    @VaadinServletConfiguration(ui = MyUI.class, productionMode = false)
    public static class MyUIServlet extends VaadinServlet {
    }
}
mvn vaadin:compile
mvn jetty:run

So it’s only working if I hit up localhost:8080. If i use 127.0.0.1:8080 or my LAN IP it is stuck.

Any idea how I can solve this?

Thank you in advance

It seems that the new Trend Micro Deep Security we rolled out the last weeks is also blocking push.
