Websocket streaming unserviceable in paper-trading

Alpaca Market Data

I keep having problems with websocket streaming that make it impossible to test my algorithm. It happens to me with the Q channel, which crashes very often giving me the most disparate errors (sometimes even not giving any, but simply not streaming the data).
The last mistake I run into is this:

 runfile ('C: /Users/Matteoc/Downloads/aplaca/exp_AM.py', wdir = 'C: / Users / Matteoc / Downloads / aplaca')
 WARNING: root: code = 1006 (connection closed abnormally [internal]), no reason
 Traceback (most recent call last):

    return f.result ()

      File "C: \ Users \ Matteoc \ anaconda3 \ lib \ asyncio \ futures.py", line 173, in result
    raise exceptions.CancelledError

    `CanceledError`

or like

T`raceback (most recent call last):`

      File "C:\Users\Matteoc\Downloads\aplaca\exp_AM.py", line 229, in <module>
        conn.run([ 'Q.AAPL', 'Q.TSLA', 'Q.GOOG', 'Q.GS', 'Q.AMZN', 'Q.SHLD', 'Q.RL', 'Q.CL', 'Q.MMM', 'Q.CVX', 'Q.NKE', 'Q.BA', 'Q.XOM', 'Q.JNJ', 'Q.PG', 'Q.SLB', 'Q.PRU', 'Q.BIIB', 'Q.WMT', 'Q.KO', 'Q.TGT', 'Q.HPQ', 'Q.PXD', 'Q.JPM' ]

      File "C:\Users\Matteoc\Downloads\aplaca\alpaca_trade_api\stream2.py", line 298, in run

      File "C:\Users\Matteoc\anaconda3\lib\asyncio\futures.py", line 173, in result
        raise exceptions.CancelledError

    CancelledError

and even when it works and streams after a while it crashes with various errors.

Where can i look for a solution?

Not sure if this is your issue, but the websockets only work with your Live key. A paper key is not valid.

I have a paper key and websockets work great on Q, T and AM channels, only sometimes they create problems. But maybe for channel A, which never works, that can be an explanation.
Thanks for the reply!
