Public projects are not being displayed.

We have GitLab set up internally (v 9.0.5). 40 private projects have been made public. When a new user logs into GitLab, there is a section at the bottom of their screen which says:

There are 40 public projects on this server. Public projects are an easy way to allow everyone to have read-only access.

They click on the "Browse projects" button.

The next page comes up with "No projects found."

Is there a configuration issue with the new user? The 40 repositories have their visibility set to "Public" and the repository, merge requests, and pipelines are all set to "Everyone with access."

What's missing?
