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

In your controller, you are using an http scheme, but I think you should be using a ws scheme, as you are using websockets. Try to use ws://localhost:3000 in your connect function.
