Access Denied while "git push" on Windows GitLab Runnner

Hello everybody,

we want to use the gitlab CI/CD to perform our release builds.
Everything works fine, but the “git push” at the end of the script wont work. :-/

remote: HTTP Basic: Access denied
fatal: Authentication failed for ‘

remote: You are not allowed to upload code.
[ERROR] fatal: unable to access ‘’: The requested URL returned error: 403

The Repository is private and so i added the Admin-Account (@root) to the Project-Members.
GitLabRunner is 11.9.0 on Windows 10 (1703)
GitLab is 11.9.8

Any Ideas?


Any solution for this? Anyone? Same issue here
