Hello,
I create my server on Ubuntu Server 18.04. I have install Gitlab locally with that tutorial:
I want to use an external nginx to get a home page.
Here is the configuration file I use:
external_url 'https://localopera-gitlab.com'
letsencrypt['enable'] = true
letsencrypt['contact_emails'] = ['half@opera.com'] # optional
nginx['redirect_http_to_https_port'] = 80
nginx['redirect_http_to_https'] = true
nginx['enable'] = false
web_server['external_users'] = ['www-data']
When I run the gitllab reconfiguration I get that error:
```
There was an error running gitlab-ctl reconfigure:
letsencrypt_certificate[localopera-gitlab.com] (letsencrypt::http_authorization line 3) had an error: RuntimeError: acme_certificate[staging] (/opt/gitlab/embedded/cookbooks/cache/cookbooks/letsencrypt/resources/certificate.rb line 20) had an error: RuntimeError: [localopera-gitlab.com] Validation failed for domain localopera-gitlab.com
```
I notice that the problem has been many time on that forum. I try all the proposed solutions but I still have the problem.
