io.sails.js catch connection refused way

Question

My question is about the way to catch socket connection refused.

Im using

"sails.io.js": "1.2.1",
"socket.io-client": "2.1.0"

According to doc

https://sailsjs.com/documentation/reference/web-sockets/socket-client/io-socket-on

There are only two system events:

io.socket.on('connect', function(){});
io.socket.on('disconnect', function(){});

Is there some other possibility to catch connection refused?
