Attempting to send on closed WebSocket
WebSocket is already in CLOSING or CLOSED state
Fixes
- 1.Check ws.readyState === WebSocket.OPEN before calling ws.send()
- 2.Queue messages during reconnection and flush when connection is re-established
- 3.Add an 'open' event handler to confirm the connection is ready before sending
