Redmine

I am trying to setup automatic git updates from github. After pushing to github repos there is the following log message:

# Log

It seems like the github redmine_hook is pinging my installation but i can not see updates/activities in redmine.

My Setup

# Github

git clone --mirror git@github.com:git_user/test.git .
