I am trying to use Spring Websocket with Sockjs and STOMPjs. As mentioned Spring Websocket Documentation, after the /info request, client send protocol upgrade request to /websocket. HTTP Status 101 expected from client.
In my application, Spring Websocket returns Http 101 as expected, however within 10 second.
Spring Websocket logs;

As you can see clearly, there is 10 seconds of silence after

I configured my WebSocketBroker with the following;
@Override public void registerStompEndpoints(StompEndpointRegistry registry) { registry .addEndpoint("/api/v3/websocket") .setHandshakeHandler(new DefaultHandshakeHandler(new TomcatRequestUpgradeStrategy())) .setAllowedOrigins("*") .withSockJS() .setClientLibraryUrl("https://cdnjs.cloudflare.com/ajax/libs/sockjs-client/1.1.4/sockjs.min.js"); } Question: Where should I focus to solve this delay? I tried different computer, different browser etc. Always ~10seconds of delay happening.
