Root Cause

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

generic

中文

代理服务器突然关闭连接，可能是由于超时或过载。

Workarounds

  1. 85% success Use a different proxy server 
    proxies = {'http': 'http://new-proxy.example.com:8080'}
requests.get('http://target.com', proxies=proxies)
  2. 75% success 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)

Dead Ends

Common approaches that don't work:

  1. Retrying immediately with the same proxy 80% fail

    The proxy may still be overloaded or resetting connections.

  2. Increasing the number of retries 70% fail

    Retries may succeed temporarily but the underlying proxy issue persists.
