I'm having problems to connect with socket.

This is the error i'm getting on browser. socket error

This is my spring socket config

@EnableWebSocketMessageBroker public class ChatSocketConfig extends AbstractWebSocketMessageBrokerConfigurer { @Override public void configureMessageBroker(MessageBrokerRegistry config) { config.enableSimpleBroker("/queue", "/topic"); config.setApplicationDestinationPrefixes("/chat"); } /** * Register the endpoint where the socket will call to connect */ @Override public void registerStompEndpoints(StompEndpointRegistry registry) { registry.addEndpoint("/chat-connect").setAllowedOrigins("*").withSockJS(); } 

I'm using sockjs-client v1.0.3, running the java application in a tomcat 8, linux ec2 on aws.

Any help on how to solve this problem?

EDITED

On server, THe only log I see is "Handshake failed due to invalid Upgrade header: null"
