根因分析

远程服务器主动拒绝连接，通常是由于防火墙规则或服务未运行。

English

The remote server is actively refusing the connection, often due to firewall rules or the service not running.

解决方案

  1. 80% 成功率 Check if the server is reachable via telnet or ping 
    telnet api.example.com 443
# If refused, contact server administrator or check firewall rules
  2. 60% 成功率 Use a different port or protocol if available 
    httpx.get('http://api.example.com:8080')  # if alternative port exists

无效尝试

常见但无效的做法:

  1. Increasing timeout to wait longer 90% 失败

    The connection is refused immediately, so a longer timeout does not help.

  2. Retrying with the same parameters 95% 失败

    The server continues to refuse connections until the underlying issue is resolved.
