Gitlab (One Click App) "port 443: Connection refused " error using Gitlab deployment method

[rayronvictor]

Has anyone already configured Gitlab One-Click App?

I've been getting the error port 443: Connection refused when using it as deployment method in other apps.

Tried this GITLAB_OMNIBUS_CONFIG, but unsuccessful:

external_url 'https://gitlab.my-org.com/';
letsencrypt['enabled'] = false;
nginx['listen_port'] = 80;
nginx['listen_https'] = false;
nginx['proxy_set_headers'] = {
  "X-Forwarded-Proto" => "https",
  "X-Forwarded-Ssl" => "on",
  "Host" => "gitlab.my-org.com",
  "X-Real-IP" => "$$remote_addr",
  "X-Forwarded-For" => "$$proxy_add_x_forwarded_for",
  "Upgrade" => "$$http_upgrade",
  "Connection" => "$$connection_upgrade"
};

Note: using HTTP (not HTTPS) works.
