Go Module Proxy

Get “https://cloud.google.com/go?go-get=1": dial tcp 172.217.24.14:443 failed time out.

When building and indexing projects on WIN10 + Goland + WSL2, I met the the error above. There’re several places where we can set the proxy to make it work.

Win10

Set the GOPROXY in Terminal

1
go env -w GOPROXY=https://goproxy.cn,direct

WSL

Set the GOPROXY in .bashrc

1
export GOPROXY=https://goproxy.cn,direct

GoLand

File - Settings - Go - Go Modules

  • Check Enable Go module integration

  • Environment : GOPROXY=https://goproxy.cn,direct
