502 error when trying to authorize Gitlab CI as an Application in Gitlab

Question

So I have a Gitlab and a Gitlab-CI server running on separate machines. I am trying to authorize CI as an application via OAuth, but when I hit the Authorize button, I get a 502 error. I've confirmed that I'm using the correct app ID and secret for the application I've created for the CI server in Gitlab, and unfortunately, the nginx and unicorn logs for gitlab aren't exactly providing me with much useful information. Has anyone seen this sort of behaviour before?

Answer 1

Did you add your gitlab server certification into gitlab-ci server?

Best.
