Solutions

  1. Check basic connectivity: curl -m 10 'https://www.alphavantage.co/query?function=TIME_SERIES_DAILY&symbol=IBM&apikey=demo'
  2. Configure proxy env vars (HTTP_PROXY/HTTPS_PROXY) if behind a corporate network
  3. Retry later or raise the request timeout / max_retries in _make_api_request
  4. Fall back to another US data source (yfinance path) when Alpha Vantage is unreachable

Example fix

# before
# default timeout, immediate failure in restricted networks
# after
import os
os.environ.setdefault('HTTPS_PROXY','http://proxy.corp:8080')
_ = _get_us_quote_from_alpha_vantage('AAPL')
Defensive patterns

Strategy: retry

Try / catch

from tradingagents.dataflows.providers.us.alpha_vantage_common import AlphaVantageAPIError
try:
    data = _make_api_request(params)
except AlphaVantageAPIError as e:
    if 'timeout' in str(e):
        time.sleep(30)
        data = _make_api_request(params)
    else:
        raise

Prevention

When it happens

Trigger: Slow or blocked network to alphavantage.co: each attempt times out, sleeps retry_delay, retries, and after max_retries raises this error.

Common situations: Corporate proxies/firewalls blocking HTTPS, DNS issues, transient upstream slowness, or an aggressive per-request timeout configured too low.
