I have two runners registered as project runner, deployed inside my own docker swarm cluster.
They have been working peacefully alongside with gitlab.com for project builds, and have been doing great on deploy tasks.
But for no reason my runners are constantly receiving Forbidden response from gitlab.com when checking for jobs. Our pipelines are on a total halt at this point.
I have looking at this issue https://gitlab.com/gitlab-org/gitlab-ce/issues/49393, but I have no way to confirm it.
Where shall I start?
