Try first with @Push(transport = Transport.WEBSOCKET_XHR)
If that doesn’t work let’s try to figure out something else. What servlet container you are using? Any proxies between?

m using jboss nd no proxies…
i tried this @Push(transport = Transport.WEBSOCKET_XHR)
but still same problam

The same problem using vaadin 14 with wildfly.
Did you solve it? what was your solution?

The same happens to me, with Vaadin 14.3.0 and Wildfly 14.0.1.

I solved the problem adding asyncSupported=true to @WebServlet, as documented in https://vaadin.com/docs/v14/flow/advanced/tutorial-push-configuration.html
