Add allowed origin:

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig implements WebSocketMessageBrokerConfigurer {

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

	@Override
	public void registerStompEndpoints(StompEndpointRegistry registry) {
		registry.addEndpoint("/gs-guide-websocket")
			.setAllowedOriginPatterns("http://localhost:8080/");
	}

}
