WebSocket connections cannot be established on edge or chrome but only on safari. what is wrong with my browser?

Question

java code with spring boot starter websocket @Configuration @EnableWebSocket public class WsConfig implements WebSocketConfigurer { @Autowired UserWsHandler userWsHandler; @Autowired UserHandlerShakeHandler userHandlerShakeHandler; @Override public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) { registry.addHandler(userWsHandler,"/loginWs") .setAllowedOriginPatterns("*"); } js . const ws = new WebSocket("ws://10.12.36.178:8080/loginWs")
