Websocket not sending any messages

Hello,

I have created a websocket and subscribed to Quotes and Bars for 30 symbols.

[
  'PEN', 'CMCSA', 'ADI', 'BKNG',
  'DE', 'AJG', 'ETR', 'BOTZ',
  'WHR', 'EXC', 'ALB', 'CEG',
  'LNT', 'DLTR', 'MSTR', 'CSCO',
  'CHTR', 'RIO', 'AA', 'CARR',
  'LIT', 'EA', 'DOW', 'BK',
  'FDX', 'AMD', 'HPE', 'AIG',
  'ED', 'CBLL'
]

I am using the alpaca.data_stream_v2 from the @alpacahq/alpaca-trade-api.

When I subscribe to the test feed, and subscribe to FAKEPACA quotes and bars everything works as expected and I can see messages coming through in my logs.

When I connect to iex and run locally or on a fly.io server, I can authenticate and subscribe, but I don’t see any event messages coming through (I’ve waited for 24hrs so I don’t think it’s because I’m out of hours)

Is this expected? How can I debug further to determine why I’m not getting quote or bar messages?
