Gitlab ci 404 error login

Hi all,

I have been trying to get gitlab-ci up and running for a test and have been unable to do so. I have installed the omnibus package, as this was a test. i have gotten gitlab running fine i am able to sign in, create repos and all the fun stuff. i can get to my ci instance but when i click on ‘login in with gitlab’ it gives a 404 error.

here is the error im getting:

this is from /var/log/gitlab/gitlab-ci/production.log

here are the configuration specific to ci:

ci_external_url ‘http://ci.git.example.com
gitlab_ci[‘gitlab_server’] = { ‘url’ => ‘http://ci.git.example.com’, ‘app_id’ => ‘secret’, ‘app_secret’ => ‘secret’}

note: i have edited out the information that i cannot share.

i have checked other posts with the same issue and none of the fixes help me in any way.

can someone please assist me in understanding what i configured wrong?
