Root Cause

Network connectivity to the Go module proxy is unavailable, often due to firewall restrictions, DNS issues, or proxy being down.

无法连接到 Go 模块代理网络，通常是由于防火墙限制、DNS 问题或代理宕机。

Workarounds

  1. 70% success Set GOPROXY=off to bypass proxy and fetch directly from VCS 
    export GOPROXY=off && go mod download
  2. 80% success Use a different proxy or direct connection 
    export GOPROXY=https://goproxy.io,direct && go mod download

Dead Ends

Common approaches that don't work:

  1. Retrying the same command repeatedly 90% fail

    Network timeout is likely persistent; retrying without fixing connectivity will continue to fail.

  2. Setting GOPROXY=https://proxy.golang.org,direct 50% fail

    This is the default; if the proxy is unreachable, it will still timeout before falling back to direct.
