remote: GitLab: You are not allowed to force push code to a protected branch on this project.

Hey,

I'm experiencing an annoying problem.

GitLab-Version: 8.14.2

Just created a new Project, I'm a Master-Member, Master-Branch is protected with Masters are allowed to Merge & Push.

But I get on git push:

$ git push
...
remote: GitLab: You are not allowed to force push code to a protected branch on this project.
...

Just unprotecting the Master-Branch allows me to push. The very strange Part is: The Init Commit works, but any further commit is rejected.

Any Hints what might be wrong?

sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production

=> Everything is fine

How to reproduce:

• Create new Project
• Init Commit
• Everything else is rejected by the Protected Branch Check
