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?

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
