Teamcity and GitLab

I’m trying to link the build status from my TeamCity server to the commit build status. At the moment it’s always skipped. I have enabled the TeamCity CI Service under the Proejct Services. I’ve tried to add a dummy gitlab-ci.yml (empty) to see what happens than, and it was pretty intresting. It waited for the TeamCity to build the project, than after it failed because the gitlab-ci.yml was empty. If i remove that file than again, it’s always skipped.

On this link: https://gitlab.com/gitlab-org/gitlab-ce/issues/3827 there is talk that GitLab-CI is enabled by default and it messes up with other CI servers. I’ve tryied disabling this as stated here: http://doc.gitlab.com/ee/ci/enable_or_disable_ci.html but than there is no build tag/bubble on the commits.

What am I doing wrong, or what am I missing?
