Url error with GitLab auth

[craig-mcmahon]

I am trying to add a package from GitLab and am getting the following error in GitLab after the redirect

The redirect URI included is not valid.

This occurs when trying to add a package, and when trying to login with GitLab from https://repo.repman.io/login

This happens to me with a self-hosted Repman install as well, regardless of which of the three URIs specified in the standalone documentation I specify in the Group Application entry in Gitlab.

https://your-domain.local/auth/gitlab/check
https://your-domain.local/register/gitlab/check
https://your-domain.local/user/token/gitlab/check

I substituted in my repman DNS for your-domain.local of course.
I also tried https://your-domain.local/* with the same results
