Error during WebSocket handshake (Unexpected response code: 400)

Question

My code perfectly working in localhost but when I put my application to sever this error happens.

WebSocket connection to 'wss://url.com/webSocket/193/uj4s3xue/websocket' failed: Error during WebSocket handshake: Unexpected response code: 400

sockjs.min.js:2 POST https://url.com/webSocket/193/e1vwalij/xhr_streaming?t=1495418202369 403 (Forbidden)

Js code :

   function connect() {
        var socket = new SockJS('/webSocket');
        stompClient = Stomp.over(socket);
        stompClient.connect({}, function (frame) {
            stompClient.debug = null;
            stompClient.subscribe('/topic/messages/' + vm.id, function (greeting) {
                refreshMessages(JSON.parse(greeting.body));
            });
        });
    } 

Java code :

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.messaging.simp.config.ChannelRegistration;
import org.springframework.messaging.simp.config.MessageBrokerRegistry;
import org.springframework.web.socket.config.annotation.AbstractWebSocketMessageBrokerConfigurer;
import org.springframework.web.socket.config.annotation.EnableWebSocketMessageBroker;
import org.springframework.web.socket.config.annotation.StompEndpointRegistry;

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {

    @Override
    public void configureMessageBroker(MessageBrokerRegistry config) {
        config.enableSimpleBroker("/topic");
        config.setApplicationDestinationPrefixes("/app");
    }

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/webSocket").setAllowedOrigins("*").withSockJS();
    }

    @Bean
    public PresenceChannelInterceptor presenceChannelInterceptor() {
        return new PresenceChannelInterceptor();
    }

    @Override
    public void configureClientInboundChannel(ChannelRegistration registration) {
        registration.setInterceptors(presenceChannelInterceptor());
    }

    @Override
    public void configureClientOutboundChannel(ChannelRegistration registration) {
        registration.taskExecutor().corePoolSize(8);
        registration.setInterceptors(presenceChannelInterceptor());
    }
}

In spring sever following exception happens :

Sever is apache2 web sever. How do I fix this issue?.

Answer 1

I slove this problem by activating ws_tunnel with

sudo a2enmod proxy_wstunnel

and making RewriteEngine On apache 000-default-le-ssl.conf file located in

/etc/apache2/sites-enabled/000-default-le-ssl.conf

  RewriteEngine On
    RewriteCond %{HTTP:Upgrade} =websocket [NC]
    RewriteRule /webSocket(.*)           ws://127.0.0.1:8080/webSocket/$1 [P,L]
