Root Cause

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

由于网络问题或代理宕机，代理服务器不可达。

Workarounds

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

Dead Ends

Common approaches that don't work:

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

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

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

    The proxy server itself is unreachable, not the port.
