Step 1. created a MR in gitlab
Step 2: it should ideally trigger MR build in jenkins
Step 3: all the gitlab server configuration is seems to be fine since the master latest build is getting pulled from gitlab to jenkins if any build job is triggered manually.
Steps 4: queue is getting refused in system log of jenkins
Steps 5: no logs I am able to get undet gitalb plugin logs in jnekins system logs but before I was able to get gitlab logs.
Step 6: i tried to degrade the gitalb plugin in jenkins but still didnt helped.
Expected Results
After MR is raised in gitlan it should trigger the MR build in jenkins
Actual Results
After MR is raised in gitlan it should trigger the MR build in jenkins but it is not triggering, system hooks of gitlab is fine because I am sneding the test for MR and it is giving 200 response
