将GOPROXY与JFrog Artifactory一起使用时找不到404

A go repository called go-feature is used in Artifactory. Go modules have been uploaded using jfrog rt gp. The env var GOPROXY is set to the value provided by Artifactory in the 'Set Me Up' window. All go get calls fail with a 404. The Artifactory version is 6.6.1

$ go get -v speechmatics.com/cockroachdbingestor@v1.0.1
go: finding speechmatics.com/cockroachdbingestor v1.0.1
go: speechmatics.com/cockroachdbingestor@v1.0.1: unexpected status (http://user:token@fake_artifactory_url.com/speechmatics/api/go/go-feature/speechmatics.com/cockroachdbingestor/@v/v1.0.1.info): 404 Not Found
go: error loading module requirements

The speechmatics/cockroachdbingestor module exists in Artifactory with the 1.0.1 version. It can be seen in the web browser.

It was expected that the go get would work.

Manually running curl against the URL returns a 404 as well. An Artifactory header is returned so the route to the server works.

After upgrading to 6.8.2 go get works.
