fixed websocket issue

[RandomLambda]

fixed compatibility issue with websocket. the open property was no longer available.

as per their documentation:

https://websockets.readthedocs.io/en/stable/reference/legacy/client.html#websockets.legacy.client.WebSocketClientProtocol.open
True when the connection is open; False otherwise.

This attribute may be used to detect disconnections. However, this approach is discouraged per the [EAFP](https://docs.python.org/3/glossary.html#term-eafp) principle. Instead, you should handle [ConnectionClosed](https://websockets.readthedocs.io/en/stable/reference/exceptions.html#websockets.exceptions.ConnectionClosed) exceptions.
