Node.js with Socket.io - Long Polling fails and throws “code”:1,“message”:“Session ID unknown” response

Question

I\'m stuck on why a node.js app that was moved to an IIS7 server is now failing. I know IIS7 doesn\'t support web sockets but my understanding was that socket.io would fall

Answer 1

for me, it was with nginx ssl http2, and it was polling, so the good config is:

 const ioSocket = io('', {
      // Send auth token on connection, you will need to DI the Auth service above
      // 'query': 'token=' + Auth.getToken()
      path: '/socket.io',
      transports: ['websocket'],
      secure: true,
    });
