Spring-Boot, Vaadin 8 application with vaadin push
@Push(transport = Transport.WEBSOCKET_XHR)
No problem if the application gets user operation without any pause. Few seconds without any user request/operation get following error on the console. This makes our error log file doodle. Thank you in advance.
Spring-boot, vaadin 8, Nginx, Plesk onyx, ubuntu 16, lets-encrypt
