Connect GitLab with Jenkins

Hi All,

We have recently installed local gitlab instance (CE), we are now in the step of connecting gitlab with our local Jenkins instance, however, i’m running into a very annoying situation, where I get permission denied while trying to run a build from Jenkins, we have set up the SSH key with the right permissions and I have put the private key from Jenkins into our gitlab instance, I’m able to clone the repo from the build server without any issue and without password, however from Jenkins itself it says permissions denied, i have went over 10-20 pages in gogole, I’m a bit lost, any ideas?
