KAS not running...maybe?

We are an enterprise user on prem using omnibus version 14.1.7-ee. Per the documentation all that is required for running the Kubernetes Agent Server (KAS) is to modify the variable gitlab_kas[‘enable’] = true and “Reconfigure GitLab”. We have done this.

We have gone through the necessary steps to successfully install the Agent into our on prem K8s cluster and can see the pod running.

When viewing the logs of the running pod/container on the cluster we are getting the following error along with some additional mod_name: reverse_tunnel no such host rpc errors:

{"level":"warn","msg":"GetConfiguration failed","error":"rpc error: code = Unavailable desc = connection error: desc =\"transport: Error while dialing failed to WebSocket dial: failed to send handshake request: Get \\\"https://kas.ourinternaldns.com\\\": dial tcp: lookup kas.ourdns.com on xx.xxx.x.xx:53: no such host\""}

If I attempt to hit the address directly https://kas.ourinternaldns.com - I get The site can’t be reached - I assume this is as intended? It’s not clear how to check that the KAS is actually running.
