WebSocket connection failed: Error during WebSocket handshake: Unexpected response code: 400

Question

I am trying to integrate Socket.io with Angular and I\'m having difficulties making a connection from the client-side to the server. I\'ve looked through other related quest

Answer 1

I solved this by changing transports from 'websocket' to 'polling'

   var socket = io.connect('xxx.xxx.xxx.xxx:8000', {
      transports: ['polling']
   });
