Loki and kubernetes gateway issues

Greetings!

I am currently trying to deploy Loki SSD on a local Kubernetes cluster following the SSD guide [Install the simple scalable Helm chart | Grafana Loki documentation]
Currently having it point to minio with nfs for testing, but will use on-prem S3 for production.

My issue is from the loki-gateway pod crashing with the below error:

/docker-entrypoint.sh: No files found in /docker-entrypoint.d/, skipping configuration
2024/06/24 13:25:01 [emerg] 1#1: host not found in resolver "kube-dns.kube-system.svc.cluster.local." in /etc/nginx/nginx.conf:33
nginx: [emerg] host not found in resolver "kube-dns.kube-system.svc.cluster.local." in /etc/nginx/nginx.conf:33

I have searched through many previous issues and their resolutions, basically suggesting that kube-dns should be coredns, or adding the clusterdomain and dnsnamespace parameters; although my Kubernetes instance has the coredns service name as kube-dns.

Our requirements is that we need to have Loki in Kubernetes externally accessible through our companies network, as we are purely on-prem with strict policies (banking).

We already have a monolithic Loki deployment on a VM for testing, and planning to integrate this SSD Loki deployment with our existing grafana-server (VM) and be able to push logs from promtail to Loki in Kubernetes.

Please let me know if I am missing anything, any help would be highly appreciated.

Here is my values.yaml file:
