根因分析

由于网络问题或代理宕机，代理服务器不可达。

English

The proxy server is unreachable due to network issues or the proxy being down.

generic

解决方案

  1. 85% 成功率 Check proxy server status and network connectivity 
    telnet proxy.example.com 8080
# If fails, contact proxy administrator or use a different proxy
  2. 70% 成功率 Use a direct connection without proxy 
    response = requests.get('http://target.com')  # remove proxies parameter

无效尝试

常见但无效的做法:

  1. Increasing the proxy timeout in the code 80% 失败

    If the proxy is down, longer timeout does not help.

  2. Using a different port on the same proxy 90% 失败

    The proxy server itself is unreachable, not the port.
