根因分析

远程服务器突然关闭TCP连接，通常是由于服务器过载或网络问题。

English

The remote server abruptly closed the TCP connection, often due to server overload or network issues.

generic

解决方案

  1. 85% 成功率 Implement retry with exponential backoff and jitter 
    import time, random
for i in range(3):
    try:
        response = httpx.get('https://unstable.example.com')
        break
    except httpx.ConnectError:
        time.sleep(2 ** i + random.uniform(0, 1))
  2. 70% 成功率 Use a connection pool with keep-alive to reduce connection resets 
    client = httpx.Client()
response = client.get('https://unstable.example.com')

无效尝试

常见但无效的做法:

  1. Retrying immediately without any delay 80% 失败

    The server may still be overloaded, causing immediate reset again.

  2. Using a different HTTP version 90% 失败

    The issue is at the TCP level, not HTTP version.
