dial tcp 34.64.4.113:443: connectex: A connection attempt failed because the connected party did not

一、问题二、分析

一、问题

用go build创建项目，拉取go第三方扩展包的时候报如下错误：

dial tcp 34.64.4.113:443: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

二、分析

查看 GOSUMDB 的配置

go env

最后是因为：set GOSUMDB=

把它关掉

go env -w GOSUMDB=off

代理推荐

go env -w GOPROXY=,direct

再次执行命令go build，成功~
