Centos Gitlab - Ssh keys not working

I’ve set up gitlab for my server, but now i’m having some problems with ssh key authentication… I’ve added a new ssh key that has been generated with puttygen in the gitlab web interface, i’m using git extensions and i’m trying to clone a repository. When i click on clone it tells me the server didn’t accept my key… Key authentication works fine on ssh users i’ve manually created, so i checked the gitlab authorized_keys file. This is what it looks like, could this be the cause? Do i need to change my sshd config to allow commands?

authorized_keys file:

############################################################################################################################################################################################################################################
############################################################################################################################################################################################################################################
command="/opt/gitlab/embedded/service/gitlab-shell/bin/gitlab-shell key-3",no-port-forwarding,no-X11-forwarding,no-agent-forwarding,no-pty (public key here)

I also checked /var/log/secure and i’m seeing this from ssh:

Hi! Can you generate open ssh key with ssh-keygen (https://gitlab.com/help/ssh/README)? I have not got to work with putty keys too.

Actually the fault was a faulty git client. There was no problem with ssh keys. I’m closing this issue.
