Compatibility with GHES

[CiucurDaniel]

I have GitHub Enterprise Server 3.18.9 provided by an external provider (different network outside of cloud space) which also provides some runners which we do not want to use because we need control over the base image and the tools installed. therefore, we have our own set of self-hosted runners based on ARC. I tried to deploy the github-actions-cache-server via helm and set both env vars:

        - name: ACTIONS_RESULTS_URL
          value: "http://cache-server-github-actions-cache-server.cache-server.svc.cluster.local:3000/"
        - name: ACTIONS_CACHE_URL
          value: "http://cache-server-github-actions-cache-server.cache-server.svc.cluster.local:3000/"

However it seems the cache action is still trying to go to a different cache server, the one from our GHES provider. This brings me to my main question.
Does the github-actions-cache-server work with GitHub Enterprise Server 3.18.9? Or could this be a different issue due to our provider already having some runners deployed?

Additional configuration bellow (as runner image we tried both the falcondev binary patch and the falcondev base image ):

FROM ghcr.io/actions/actions-runner:2.334.0

# Apply falcondev binary patch
RUN sed -i 's/\x41\x00\x43\x00\x54\x00\x49\x00\x4F\x00\x4E\x00\x53\x00\x5F\x00\x52\x00\x45\x00\x53\x00\x55\x00\x4C\x00\x54\x00\x53\x00\x5F\x00\x55\x00\x52\x00\x4C\x00/\x41\x00\x43\x00\x54\x00\x49\x00\x4F\x00\x4E\x00\x53\x00\x5F\x00\x52\x00\x45\x00\x53\x00\x55\x00\x4C\x00\x54\x00\x53\x00\x5F\x00\x4F\x00\x52\x00\x4C\x00/g' /home/runner/bin/Runner.Worker.dll
