SSL letsencrypt

I was wondering if someone could shed some light on the issue im having on letsencrypt. Currently have working gitlab internally. but i want to to use to access with letsencrypt. I was looking at

and on letsencrypt section this is what i have

external_url ''
letsencrypt['enable'] = true

letsencrypt[‘contact_emails’] =
letsencrypt[‘group’] = ‘root’
letsencrypt[‘key_size’] = 2048
letsencrypt[‘owner’] = ‘root’
letsencrypt[‘wwwroot’] = ‘/var/opt/gitlab/nginx/www’

then i run this

        gitlab-ctl reconfigure

but when i access does not show up, but if i use it works. then i tried using the old guide
but i get this

            The client lacks sufficient authorization

any ideas?

Thank you

BUMP? anyone?

Solved: had to disable the email part for it to work
