When generating a new tag repository, I'm getting an HTTP Error 401. I think the credentials are not being sent on the command.

If I do the same from shell, works properly

These are the logs:

> git tag -l TAG-39 # timeout=10
> git tag -a -f -m http://oclrh65c109.isbcloud.isban.corp:9080/jenkins/job/ReleaseLokiAll/39/ TAG-39 # timeout=10
