Jenkins GitLab Config for Posting Status of Build to GitLab - 404 Bad Request

[Ryan]

Hi,

  I've got our Jenkins setup with the GitLab plugin v 1.5.11 and I'm trying to get it to communicate with private GitLab EE v 11.9.0.

  Jenkins can do all the basic stuff with git here.. Clone, Webhooks to initiate build, etc., but I'm trying to set it up such that it tells gitlab the status of the branch's build.  I thought that the Jenkins GitLab plugin could help with this.  

   When I setup the Connection in Jenkins Configuration, and click Test Connection - I just get a 404 Bad Request... 

   When I check the logs, the most notable thing I see is "Warning: no suitable certificate found - continuing without client authentication".

    Any ideas here?

Thanks

Not familiar with GitLab config options, so, pls ignore if this note is irrelevant.

Will it help if the user (that does the build, can clone the repo, etc.) as one of the members in the specific repo within GitLab?
