Solutions

1. Reproduce the underlying error: python -c "import requests; print(requests.get('https://www.alphavantage.co/query', params={'function':'GLOBAL_QUOTE','symbol':'IBM','apikey':'demo'}).status_code)"
2. Fix proxy/TLS/DNS issues surfaced by the embedded exception {e}
3. Increase max_retries/retry_delay for transient outages
4. Add a fallback datasource in the caller

Example fix

# before
_ = _make_api_request(params)  # raises with connection error
# after
try:
    _ = _make_api_request(params)
except AlphaVantageAPIError:
    _ = _get_us_quote_from_yfinance(symbol)  # fallback

from tradingagents.dataflows.providers.us.alpha_vantage_common import AlphaVantageAPIError
try:
    data = _make_api_request(params)
except AlphaVantageAPIError as e:
    logger.error('AV failed: %s', e)
    data = _get_us_quote_from_yfinance(symbol)

When it happens

Trigger: DNS resolution failure for alphavantage.co, connection resets, proxy misconfiguration, or server-side 5xx — recurring across all retry attempts.

Common situations: Flaky networks in containers, wrong HTTPS_PROXY, certificate verification failures, or Alpha Vantage outage windows.
