[X] I've read the Changelog before submitting this issue and I'm sure it's not due to any recently-introduced backward-incompatible changes

To Reproduce

1. Deployed AKS cluster (done through terraform)
2. Rolled helm charts on (done through terraform)
3. Verify connection is established to github
4. Start github actions job on runner
5. Nothing is happening

Describe the bug

We are running a github enterprise server (version 3.12.4) which is hosted in Azure as well. It's configured as such that we need a custom self-signed certificate to properly authenticate.

The controller and listener pod is spinning up without showing errors.

The runner pod doesn't seem to be scaling, but it's spinning up according to the minimum amount of pods according to the helm configuration. However i can see that it sees that a job is available and tries to pick it up, but failing due to a PartialChain error when trying to establish SSL connection.

If i run a bash to the runner pod it self, and execute the "run.sh" script it does pick up the job and begin running it.

Describe the expected behavior

Runner will automatically pick up the available jobs and start running them.
