Root Cause

The Go module proxy has rate-limited your IP due to excessive requests in a short period.

generic

中文

Go 模块代理因短时间内请求过多而对您的 IP 进行了速率限制。

Workarounds

  1. 80% success Wait for the rate limit window to expire (typically a few minutes). 
    Pause all Go commands for 5-10 minutes, then retry.
  2. 90% success Use a different proxy or direct source with GOPROXY=direct. 
    Set 'export GOPROXY=direct' to bypass the proxy and fetch directly from VCS.

Dead Ends

Common approaches that don't work:

  1. Increasing parallelism in build with -p flag. 100% fail

    More parallel requests will worsen the rate limit.

  2. Using a different proxy without waiting. 50% fail

    If the same IP is used, the rate limit may still apply.
