I followed a tutorial on how to make a multiplayer tetris game, here is the repo: https://github.com/Leftier/tetris
It worked just fine on localhost so I tried to deploy it in heroku (https://tetrixtest.herokuapp.com/ --ASD to move Q/E to rotate) but I get the following error:
WebSocket connection to 'wss://tetrixtest.herokuapp.com/' failed: Error during WebSocket handshake: Unexpected response code: 200
while trying to create the webSocket in this line (connection-manager.js line 14):
this.conn = new WebSocket(`wss://${window.location.hostname}:${window.location.port}`)
I don't know much about webSockets, at first I thought that heroku was not able to handle websockets but that wasn't the case so I tried using the link directly as an argument instead of reading it from the browser but still the same issue.
I would like some clues/hints about why does this happens, I searched in google and github, but I only found issues related to socket.io
