Gitlab with redmine service : connection informations

Question

I have a Redmine and a GitLab. I try to configure the Redmine service in Gitlab but it only asks for 3 Redmine URLs (projectURL, issueURL newIssueURL) and no login / password nor API Key.

Obviously the "Test settings" button raises an error:

We tried to send a request to the provided URL but an error occurred "

Is it possible to use a "private" redmine with gitlab?

Answer 1

I made it work by adding a missing entry to redmine host in /etc/hosts

But finally it is just a module to display a redmine link inside gitlab, not a "true integration". When you click to issues it redirect you to redmine.

That is not what I want
