Server rejected WebSocket connection Error: HTTP 404

Alpaca Account Troubleshooting Random
1

Hi, I’m new to Alpaca API and here I’m attempting to get OHLCV bar data for the crypto coin TIAUSDT, so i can paper trade it with my own strategy.

I’ve made sure the url and api is correct.

Any help is deeply appreciated. Thanks in advance :smile:


import asyncio
import logging
import time
from alpaca_trade_api.stream import Stream
from alpaca_trade_api.common import URL

logging.basicConfig(format='%(asctime)s %(message)s', level=logging.INFO)

def run_connection(conn):
    try:
        conn.run()
    except KeyboardInterrupt:
        print("Interrupted execution by user")
        asyncio.get_event_loop().run_until_complete(conn.stop_ws())
        exit(0)
    except Exception as e:
        print(f'Exception from websocket connection: {e}')
    finally:
        print("Trying to re-establish connection")
        time.sleep(3)
        run_connection(conn)

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

if __name__ == '__main__':
    conn = Stream(api_key,
                  api_secret,
                  base_url=URL('https://paper-api.alpaca.markets'))

    ohlc_data = conn.subscribe_crypto_bars(print_quote, 'BTCUSD')
    on_crypto_bar(ohlc_data)
    run_connection(conn)

Here’s the traceback:
