We have websocket microservice running in dev server behind gateway. Here is the code piece that am using to connect to it using sockjs.

function connect() {
            var socket = new SockJS('https://dev.my.net/api/v1/websocket/app');
            stompClient = Stomp.over(socket);
            stompClient.connect({}, function(frame) {
                setConnected(true);
                console.log('Connected: ' + frame);
                stompClient.subscribe('/topic', function(messageOutput) {
                    showMessageOutput(JSON.parse(messageOutput.body));
                });
            });

Here is the spring boot configuration for websocket :

@Configuration
@EnableWebSocketMessageBroker
public class WebsocketConfig implements WebSocketMessageBrokerConfigurer {


final WebSocketHandshakeAuthInterceptor webSocketHandshakeAuthInterceptor;

@Autowired
public WebsocketConfig(WebSocketHandshakeAuthInterceptor webSocketHandshakeAuthInterceptor) {
    this.webSocketHandshakeAuthInterceptor = webSocketHandshakeAuthInterceptor;
}

@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
    registry.addEndpoint("/app")
            .addInterceptors(webSocketHandshakeAuthInterceptor)
            .setAllowedOriginPatterns("*");
    registry.addEndpoint("/app")
            .addInterceptors(webSocketHandshakeAuthInterceptor)
            .setAllowedOriginPatterns("*").withSockJS()
            .setSupressCors(true);
}

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

}

The error am getting in console :

   WebSocket connection to 'wss://dev.my.net/api/v1/websocket/app/646/x5eauxus/websocket?Authorisation=Bearer asdfghjkl' failed:

Can someone tell me why am getting 401 errors ? I know its trying to use all fallback options possible to connect using sockjs .
