根因分析

远程服务器的 SSL 证书无效、已过期或不受系统 CA 包信任。

English

The SSL certificate of the remote server is invalid, expired, or not trusted by the system's CA bundle.

generic

解决方案

  1. 80% 成功率 Update system CA certificates 
    pip install certifi
# or update OS CA bundle
  2. 90% 成功率 Provide a custom SSL context with trusted certificates 
    import ssl
ssl_context = ssl.create_default_context(cafile='/path/to/cert.pem')
async with aiohttp.ClientSession(connector=aiohttp.TCPConnector(ssl=ssl_context)) as session:

无效尝试

常见但无效的做法:

  1. Disabling SSL verification entirely with ssl=False 30% 失败

    This bypasses security and may lead to man-in-the-middle attacks; also not recommended for production.

  2. Using a custom SSL context without proper certificates 60% 失败

    If the custom context is not configured correctly, the error persists.
