nginx - 无法解包数据，无效状态 CLOSED

Question

Spring-Boot，带有 vaadin 推送的 Vaadin 8 应用程序

@Push(transport = Transport.WEBSOCKET_XHR)

如果应用程序在没有任何暂停的情况下获取用户操作，则没有问题。如果没有任何用户请求/操作，几秒钟后控制台上就会出现以下错误。这使得我们的错误日志文件变成涂鸦。预先感谢您。

Spring-boot、vaadin 8、Nginx、Plesk onyx、ubuntu 16、let-crypt

nginx 配置:

location / {
        proxy_pass https://ip:port;
        proxy_set_header Host             $host;
        proxy_set_header X-Real-IP        $remote_addr;
        proxy_set_header X-Forwarded-For  $proxy_add_x_forwarded_for;
        proxy_set_header X-Accel-Internal /internal-nginx-static-location;
        access_log off;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
}

Spring Boot application.properties

server.tomcat.remote_ip_header = x-forwarded-for
server.tomcat.protocol_header = x-forwarded-proto
server.tomcat.port-header = X-Forwarded-Port    
server.use-forward-headers = true

在本地主机中:
