Report #17825

[bug\_fix] go: github.com/myorg/[email protected]: reading https://proxy.golang.org/github.com/myorg/private-repo/@v/v0.0.0.zip: 404 Not Found

Set the GOPRIVATE environment variable to include the private repository path \(e.g., export GOPRIVATE=github.com/myorg/\*\) so the go command bypasses the public proxy and checksum database, fetching directly from the source VCS.

Journey Context:
A developer adds an import for an internal private repository and runs 'go mod tidy'. The command fails with a 404 Not Found from proxy.golang.org. They verify their Git SSH keys and can manually clone the repository, so they are confused why Go cannot fetch it. They eventually realize that since Go 1.13, the go command defaults to downloading modules via the public Go module proxy and checksum database. Since the private repo isn't public, the proxy returns 404. By setting GOPRIVATE, they instruct the Go toolchain to bypass the public proxy and checksum DB for matching module paths, falling back to direct VCS access which succeeds via their configured Git credentials.
