Root Cause

The server returns a redirect loop (or more than max_redirects hops), typically due to HTTP-to-HTTPS misconfiguration or cookie/session requirements.

中文

服务器返回重定向循环（或超过 max_redirects 跳数），通常由 HTTP 到 HTTPS 配置错误或 cookie/会话要求引起。

Workarounds

  1. 88% success 
    async with session.get(url, allow_redirects=False) as r:
    print(r.status, r.headers.get('Location'))
# follow manually and correct the base URL or auth cookie
  2. 75% success 
    session.cookie_jar.update_cookies({'session': token})
async with session.get(url) as r:
    ...

Dead Ends

Common approaches that don't work:

  1. 80% fail

    A true redirect loop never terminates; raising the limit only delays the failure and wastes requests.

  2. 65% fail

    You then receive the 3xx response body instead of the target content, so the fetch still fails functionally.
