As the title states, I can\'t clone a repository from a Gitlab 6 server even though the ssh seems to work.
When trying to clone, it looks like this:
git
I had the same problem recently with my private GitLab-CE hosted server. Reconfiguring the GitLab saved me. I have tried editing the local config file and adding the host also, but it didn't work. This worked for me.
sudo gitlab-ctl reconfigure
