根因分析

由于网络问题、防火墙或服务器宕机，服务器不可达。

English

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

generic

解决方案

  1. 80% 成功率 Check network connectivity using ping or traceroute 
    ping slow.example.com
# If unreachable, check firewall or VPN settings
  2. 70% 成功率 Use a different network interface or proxy 
    proxies = {'http': 'http://proxy.example.com:8080'}
requests.get('http://slow.example.com', proxies=proxies)

无效尝试

常见但无效的做法:

  1. Reducing the timeout value to fail faster 80% 失败

    Does not solve the connectivity issue.

  2. Using a different user-agent 95% 失败

    The problem is network-level, not application-level.
