[corpix]

Nixpkgs version

• Unstable (25.05)

Describe the bug

Got tls handshake timeouts with latest go version (1.24.1), while 1.23.7 works fine.

Steps to reproduce

1.24.1:

 ~ # rm -rf /tmp/athens073634548; mkdir -p /tmp/athens073634548 ; GOPATH=/tmp/athens073634548 GOCACHE=/tmp/athens073634548/cache GO111MODULE=on GODEBUG=netdns=cgo,httptrace=1,tlshandshake=1,http2client=1 GOFLAGS=-v GOPROXY=https://proxy.golang.org,direct /nix/store/cfjhl0kn7xc65466pha9fkrvigw3g72n-go-1.24.1/bin/go mod download -json golang.org/x/tools@v0.25.0
{
	"Path": "golang.org/x/tools",
	"Version": "v0.25.0",
	"Error": "golang.org/x/tools@v0.25.0: Get \"https://proxy.golang.org/golang.org/x/tools/@v/v0.25.0.info\": net/http: TLS handshake timeout"
}

1.23.7:

 ~ # rm -rf /tmp/athens073634548; mkdir -p /tmp/athens073634548 ; GOPATH=/tmp/athens073634548 GOCACHE=/tmp/athens073634548/cache GO111MODULE=on GODEBUG=netdns=cgo,httptrace=1,tlshandshake=1,http2client=1 GOFLAGS=-v GOPROXY=https://proxy.golang.org,direct /nix/store/valwknmr0qzxq70h4ijm9w1jvgc3grsp-go-1.23.7/bin/go mod download -json golang.org/x/tools@v0.25.0

	"Sum": "h1:oFU9pkj/iJgs+0DT+VMHrx+oBKs/LJMV+Uvg78sl+fE=",
	"GoModSum": "h1:/vtpO8WL1N9cQC3FN5zPqb//fRXskFHbLKk4OW1Q7rg=",

		"Ref": "refs/tags/v0.25.0"
	}
}

Expected behaviour

No tls handhake timeouts, I expecting go mod download to finish successfully just like it does in 1.23.7
