status:active but still "Failed to authneticate"

[gilbh]

I really like your scalping strategy and Python implementation!

I have a live account and a paper account, and regularly work with Polygon. However, when I try to run your code with my paper account, I get the following error:

c:\users\gil\envs\utils\lib\site-packages\alpaca_trade_api\stream2.py in _connect(self)
     44             status = msg.get('data').get('status')
     45             if status != 'authorized':
---> 46                 raise ValueError(
     47                     (f"Invalid Alpaca API credentials, Failed to "
     48                      f"authenticate: {msg}")

ValueError: Invalid Alpaca API credentials, Failed to authenticate: {'stream': 'authorization', 'data': {'action': 'authenticate', 'message': 'access key verification failed', 'status': 'unauthorized'}}

-- this is despite the fact my account is active:

ipdb> api.get_account()

Can you please advise?
