根因分析

代理服务器突然关闭连接，可能是由于超时或过载。

English

The proxy server abruptly closed the connection, possibly due to timeout or overload.

解决方案

  1. 85% 成功率 Use a different proxy server 
    proxies = {'http': 'http://new-proxy.example.com:8080'}
requests.get('http://target.com', proxies=proxies)
  2. 75% 成功率 Add a delay between connection attempts to avoid overwhelming the proxy 
    import time
for _ in range(3):
    try:
        response = requests.get('http://target.com', proxies=proxies)
        break
    except requests.exceptions.ConnectionError:
        time.sleep(2)

无效尝试

常见但无效的做法:

  1. Retrying immediately with the same proxy 80% 失败

    The proxy may still be overloaded or resetting connections.

  2. Increasing the number of retries 70% 失败

    Retries may succeed temporarily but the underlying proxy issue persists.
