errno 111 with alpaca websocket : Forums : PythonAnywhere

hello,

I'm using a Python script to connect to the Alpaca Market API (which is on the whitelist) from pythonanywhere via WebSocket, but unfortunately, I'm encountering error number 111, connectionRefusedError.

The code works fine when I run it from my personal computer, but when I execute it from PythonAnywhere, I get this error.

Here's the code:

########
import configPAP as config
import datetime
from alpaca_trade_api.common import URL
from alpaca_trade_api.stream import Stream

async def trade_callback(t):
    print('trade', t)
    time.sleep(50)

async def quote_callback(q):
    print('quote', q)


# Initiate Class Instance
stream = Stream(config.API_KEY,
                config.SECRET_KEY,
                base_url=URL('https://paper-api.alpaca.markets'),
                data_feed='iex',  # <- replace to 'sip' if you have PRO subscription
                    websocket_params= {'ping_interval': 50},)

# subscribing to event
stream.subscribe_trades(trade_callback, 'AAPL')
stream.subscribe_quotes(quote_callback, 'IBM')

stream.run()

" AND here's the encountered error : "

error during websocket communication:

    raise OSError(err, f'Connect call failed {address}')

So, what do you think about this error ? what's wrong with this code ?

Thank you for your responses.
