That is why a WebSocket client will not be able to successfully connect to a [Socket.IO](http://Socket.IO) server, and a [Socket.IO](http://Socket.IO) client will not be able to connect to a plain WebSocket server either.

If you want to use EventSub with Websockets, you have to do it with a Websocket client, not [socket.io](http://socket.io) as that’s not a websocket client.

No, because socket.io-client isn’t a Websocket client, it’s a [socket.io](http://socket.io) client.

The Websockets transport for EventSub requires you to use a websocket client.
