Cannot connect to connect.websocket.in

The last 2 days, I'm getting this error:

```
WebSocket connection to 'wss://connect.websocket.in/testroom' failed:
  Error during WebSocket handshake: Unexpected response code: 502
```

So I've implemented an equivalent https://github.com/thgh/websocket-room
Available at `ws://websocket-room.now.sh`
