Root Cause

HTTP client request timed out because the server took longer than the configured Timeout or context deadline to send response headers.

中文

HTTP客户端请求超时，因为服务器发送响应标头的时间超过了配置的超时时间或上下文截止时间。

  2. Implement retry logic with exponential backoff and jitter for transient network issues

Dead Ends

Common approaches that don't work:

  1. 70% fail

    This masks the underlying issue; if the server is slow or misconfigured, the request still fails eventually or blocks resources.

  2. 85% fail

    Retrying without backoff can overwhelm the server and cause cascading failures.
