Re-opening because the issue is being mis-treated as mis-configuration, BUT clearly, it is a bug in "go get" (or go mod tidy) discovery phase.

Please don't close this without fully understanding the details.

gitlab works without the .git suffixes (example https://gitlab.com/gitlab-org/gitlab/-/issues/29629). if you have problems, it's because of other reasons.

Unlike many projects, the Go project does not use GitHub Issues for general discussion or asking questions. GitHub Issues are used for tracking bugs and proposals only.

For questions please refer to https://github.com/golang/go/wiki/Questions

That thread in your shared link discusses "git clone" which I also specified works. "go get" or "go mod tidy" is the one not working, discussed by this bug report. I am re-opening the case.
