I need a node.js and socket.io and cocos js expert

I'm building a game that needs to connect to a server via socket.io. it will be a multiplayer game for facebook instant games. So far i can get the server to accept a connection from the game but i don't understand the web socket handshake and the connection keeps closing and re opening. I also have a cors issue i cant seem to solve. I really want an expert who can point out where i'm going wrong via team viewer. I will be doing the coding, you will be watching giving me instructions. Only apply if you are a programmer. Strictly no agents!
