I have been using Gitlab for a while now and, judging from their login page, which runs gitlab, I should be able to use multiple omniauth providers. It seems, however, that i cannot. I have been trying this for several hours, without any result.

My gitlab.rb:

# General Settings
external_url "https://gitlab.stsosz.io"

# Ruby on Rails Settings
gitlab_rails['gitlab_email_from'] = "gitlab@stsosz.io"
gitlab_rails['gitlab_support_email'] = "support@stsosz.io"

## TImezone Setting
gitlab_rails['time_zone'] = 'EST'

## Backup Options
gitlab_rails['backup_keep_time'] = 604800

## Sign-in Page Options
gitlab_rails['gitlab_signup_enabled'] = true
gitlab_rails['omniauth_enabled'] = true
gitlab_rails['omniauth_allow_single_sign_on'] = true
gitlab_rails['omniauth_block_auto_created_users'] = false

gitlab_rails['omniauth_providers'] = [
    {
      "name" => "github",
      "app_id" => "Removed for Security",
      "app_secret" => "Removed for Security",
      "url" => "https://github.com/",
      "args" => { "scope" => "user:email"}
    }
    {
      "name" => "google_oauth2",
      "app_id" => "Removed for Security",
      "app_secret" => "Removed for Security",
      "args" => { "access_type" => "offline", "approval_prompt" => "" }
    }
]

# Nginx Settings
nginx['redirect_http_to_https'] = true
nginx['ssl_certificate'] = "/etc/gitlab/ssl/ssl-gitlab.unified.crt"
nginx['ssl_certificate_key'] = "/etc/gitlab/ssl/ssl-gitlab.key"
# nginx['custom_nginx_config'] = "include /etc/gitlab/nginx_custom/stsosz_io.conf;"

# Unicorn Settings
unicorn['worker_processes'] = 5

Here is the output of sudo gitlab-ctl reconfigure
