[BUG] Websocket sometimes get lose connection on container

[xncbf]

[E:pyppeteer.connection] connection unexpectedly closed
Task exception was never retrieved

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

Traceback (most recent call last):
  File "/usr/local/lib/python3.7/site-packages/pyppeteer/connection.py", line 73, in _async_send
    await self.connection.send(msg)

    await self.ensure_open()
  File "/usr/local/lib/python3.7/site-packages/websockets/protocol.py", line 771, 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:

Traceback (most recent call last):
  File "/usr/local/lib/python3.7/site-packages/pyppeteer/connection.py", line 79, in _async_send
    await self.dispose()

Above is container error logs

Hi, I have similar problem. I've used ws.send in a loop.run_until_complete and after sending some amount of data, I got this error: File "<ipython-input-1-2de4519b4e62>", line 144, in service_connection await ws.send(message) File "Local_Addr\lib\site-packages\websockets\protocol.py", line 530, in send await self.ensure_open() File "Local_Addr\lib\site-packages\websockets\protocol.py", line 779, in ensure_open await asyncio.shield(self.close_connection_task) File "Local_Addr\lib\asyncio\futures.py", line 260, in __await__ yield self # This tells Task to wait for completion

I also checked not to send any data if connection is closed ( by "ws.closed") and it didn't make any difference. I'm really in hurry and any help will be appreciated.
