Selfhosted GitLab Pages showing 404

Selfhosted GitLab Pages showing 404 page not found.

We have deployed gitlab using docker image gitlab/gitlab-ce:12.6.4-ce.0. We have created runner using another docker image gitlab/gitlab-runner:latest and we have registered the gitlab project URL via gitlab runner. We could deploy GitLab Page successfully via pipeline. But the GitLab Page is showing “404 page not found.” The below error is getting on trafic while accessing the URL : https://<pageurl>/ops-management.

i have a very similar setup…docker with gitlab + docker CI. I get successful completion of the runner but also get 404 errors.
2 questions:

  1. did you ever get this resolved?
  2. are you hosting Pages and Gitlab on the same host/container? do you have 2 IPs setup (one for gitlab and one for pages)
