websocket connection closed

[reza-yb]

websocket is not reliable and sometimes when an exception happens it does not restart. traceback of the exception that is happening from time to time is as follows:

Traceback (most recent call last):
  File "/usr/local/lib/python3.9/site-packages/websockets/legacy/protocol.py", line 750, in transfer_data
    message = await self.read_message()

    frame = await self.read_frame(max_size)

    data = await reader(2)

    raise exceptions.IncompleteReadError(incomplete, n)
asyncio.exceptions.IncompleteReadError: 0 bytes read on a total of 2 expected bytes

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/usr/local/lib/python3.9/site-packages/kucoin_futures/websocket/websocket.py", line 43, in _run
    _msg = await asyncio.wait_for(self._socket.recv(), timeout=self.get_ws_pingtimeout())
  File "/usr/local/lib/python3.9/asyncio/tasks.py", line 481, in wait_for
    return fut.result()
  File "/usr/local/lib/python3.9/site-packages/websockets/legacy/protocol.py", line 421, in recv
    await self.ensure_open()
  File "/usr/local/lib/python3.9/site-packages/websockets/legacy/protocol.py", line 726, in ensure_open
    raise self.connection_closed_exc()
websockets.exceptions.ConnectionClosedError: code = 1006 (connection closed abnormally [internal]), no reason

During handling of the above exception, another exception occurred:
