I created a simple Socket.io server, if I test it using the chrome application "Socketio Checker" it returns that everything is working.

However, when I try to connect through my client, it always returns that I am not connected and also the "connect" events are not fired.

I'm using the "socketio-client" lib in Vuejs.

My code:

const sock = io(`http://localhost:3005`, {reconnect: true, transports: ['websocket', 'polling', 'flashsocket']});
        console.log(" RES =>", sock)
        console.log("HERE 22")        
        console.log('check 1', sock.connected);
        sock.on("connect", function(socket){ 
          console.log("HERE???")
          console.log(socket.connected); // true
          socket.emit('register', "810f5f4a07b9631107a7bbad39e455-0", "123");
        });

        sock.on('disconnect', function(socket) {
          console.log("Socket disconnected.");
          socket.socket.reconnect();
        })

        sock.on("connection", (socket) => {
          console.log("TADHFSHDFHDSHF", socket.id); // x8WIv7-mJelg7on_ALbx
        });

My response:

---- start ----
RES => Socket {connected: false, disconnected: true, receiveBuffer: Array(0), sendBuffer: Array(0), ids: 0, …}
HERE 22
check 1 false
---- the end ----
